Title: Next (personal) project - Moto Morini 3 1/2 Strada
Post by: Antietam Classic Cycle on October 20, 2019, 09:39:34 PM
Picked this up for $300. Missing parts and there's no title, but the engine turns over and has compression. The tires are original, so it's likely it doesn't have many miles on it (speedometer is one of the things missing). Tank is dent free and solid. What form it takes depends on if I can find the parts to resurrect it back to stock-ish spec. If not, then it'll go a little less original...

looks like a 1977 model , over here only the sport had a steering damper, but that might be different for other markets.

I was thinking '77 also due to the diamond pattern on the seat cover. All of our Morinis seem to have been equipped with a steering damper.

Unloaded it from the van and assessed the condition a bit. Engine has clean oil in it, transmission shifts through the gears perfectly. Tires aren't original like I thought - date codes are for 1982. More photos.

Seat cover is toast of course, but the foam looks good.

Solid pan too.

Tool tray is still in place. Wiring is for the signals.
(https://i.ibb.co/Fsj7nkK/Morini-assessment-005.jpg) (https://ibb.co/Fsj7nkK)

Underside of the tank is rust free and solid. 
(https://i.ibb.co/vY14ty2/Morini-assessment-007.jpg) (https://ibb.co/vY14ty2)

The inside is rusted, but that's no biggie. 
(https://i.ibb.co/mBbD2zg/Morini-assessment-008.jpg) (https://ibb.co/mBbD2zg)

All of the wiring appears intact.
(https://i.ibb.co/K0B2cQ2/Morini-assessment-009.jpg) (https://ibb.co/K0B2cQ2)

I was very happy to find the key in the box of bits.

The transducers are still in place.

CEV "snuffbox" for the headlight, signals and horn.

The forks tubes look good in the travel area.

Just a little rust where the headlight ears attach. 
(https://i.ibb.co/BwFh4Mz/Morini-assessment-014.jpg) (https://ibb.co/BwFh4Mz)

Missing the "half-rings" for the rear cylinder headpipe. 
(https://i.ibb.co/SV8HM6H/Morini-assessment-015.jpg) (https://ibb.co/SV8HM6H)

Another clue about what year it is - "12/76" is cast into the wheel.
(https://i.ibb.co/R2SWBGg/Morini-assessment-016.jpg) (https://ibb.co/R2SWBGg)

Some of the bits in the box: warning light panel, gauge mount, gas cap, most of a taillight lens and the clutch lever assembly.
(https://i.ibb.co/5XZRH98/Morini-assessment-018.jpg) (https://ibb.co/5XZRH98)

Stuck the cap back on the tank...
(https://i.ibb.co/r7M1Nnb/Morini-assessment-019.jpg) (https://ibb.co/r7M1Nnb)

...and the lever back on the 'bars. Hooked up the cable - clutch works!
(https://i.ibb.co/17gSrzK/Morini-assessment-020.jpg) (https://ibb.co/17gSrzK)

Once upon a time, it had crashbars mounted up - there are dings in the frame tubes from the u-bolts.

Put the tank and seat back on in their proper positions.

Cleaned and lightly buffed the tank. Looks pretty good.

Unfortunately, it does have a dent in the right front corner.

I hope you have lots of popcorn! Not much will happen for a while, although I might get it up on a lift soon and give the engine a once over and see if it'll run. Definitely will need a timing belt replacement and I'll want to check a long "laundry list" of items before the attempt. If it runs and doesn't make any "funny" noises, then it could happen a lot sooner.

It is a Sport. I can see the "S" at the right base of the front cylinder. The front mudguard is the short Sport version, and the steering damper confirms everything. The tank paint scheme seems like a 1978 or 1979 model.

It appears to be in very good condition overall, all things considered. Obviously, a new cam belt is the first thing to get. Wheel bearings and steering head bearings also should be checked. The rest will be a matter of cleaning and the usual replacements. The nice thing about Morinis is that the factory used top-shelf components for their day. They need very little to keep running well.

I would say that you got a very nice deal. Enjoy the restoration!

Not a Sport. There is no "S", just dirt.  :wink: The front mudguard has been bobbed - the edge is very rough. Steering dampers were o.e. on all 3 1/2 Morinis sold in the US, not just Sports.

The diamond pattern seat cover means this is pre-'78. Along with the "12/76" cast into the wheels, it's reasonable to assume that it's a '77.

This isn't my first Morini: I've owned three previously (500 Strada, '86 350 K2 and '85 350 K2). Finished restoration of a very early 3 1/2 Sport last year and am currently starting on the second one from the same customer.

I purchased the missing exhaust pipe half rings on ebay this morning and a timing belt is on my McMaster-Carr order. When time allows, I'll "go over" the engine and ignition system, rebuild the carbs, etc. and see if it'll run. The results of that will determine how quickly the "restoration" happens, but it will eventually be done. There's also the chance it might go a different, completely non-original direction.

Looking forward to hear how you make out with it.
I got back from my European motorcycle tour this week and a pair of re-sleeved Morini 500 cylinders from LA Sleeve were waiting for me.
I fitted the new pistons, rings and fitted the cylinders and heads back on today.
Should solve the low compression issue I had trying to save the old over bored cylinders and poorly fitted pistons and rings the previous owner fitted.

I've collected a few parts, bought some and have more coming this week.

A couple of years ago I bought a new-old-stock Veglia speedometer on ebay for $60. It's been stored in a bin since then waiting a project that needed. It may not be the correct one for the Morini (no name on the face, only goes to 80 mph and has a tripmeter) but it's the correct ratio, so I'm using it.

I decided to use a Magura (V7 Sport) throttle I had in my stash, rather than spend the $$ for the correct Verlicchi one.

Found a good used horn and mounting bracket, bought the exhaust half-rings on ebay from Herdan Corp., and McMaster-Carr supplied the timing belt (same one that worked perfectly on my 350 K2).

Gaining...

Maybe I missed it but are you going through the engine in this...?

You have me beat on the registration tag too, the V1000 was last on the road in '91 according to the plate on it.

"To Be Determined". I'll only tear into it if necessary. It turns over and has compression, oil looks fresh, shifts through the gears and the clutch works. Once I pop the rocker covers off and drain the oil (to see if there any shrapnel on the filter screen or in the bottom of the case), I'll know if I need to dig in or not. I bought the gasket set mostly for the rocker cover, manifold, exhaust and oil strainer gaskets. It was less costly than buying them individually.

My new (old stock) MZ - Grimeca master cylinder arrived today, only $50 on ebay. It's not the original type (which would have had a round reservoir) or the original piston diameter (which at 16 mm was way too big anyway) - this one is 11 mm and will have a more favorable ratio for better feel and braking power. It has an integrated mirror mount and mechanical brake light switch so I can run one hose directly from the master cylinder to the caliper. The original setup was two hoses (upper and lower) with a manifold and pressure switch in between.

I decided to contact the person that owned the Morini before Ron K., who I bought it from. Glad I did - he gave me this bit of bad news: "After I got the bike from Bob I was going to get it running. Drained the crankcase oil and a ball bearing came out."  :sad: Explains why it has fresh oil in it.

Sounds like a full engine teardown will be necessary after all. It's not that big of a deal really - once out of the frame, it usually takes me about two to three hours to strip one down completely. "Better safe than sorry". All of the ball bearings are commonly available, so is the upgraded roller bearing on the timing side, less than $100 for all of them. Rod bearing is a plain type and available from Mdina Italia.

Sundays are my "me day", so this afternoon I rolled the Morini up onto the lift and had at it. The engine was out in 1.5 hours, disassembled to to the main cases in another 1.75. Nothing really super stuck except for the exhaust headpipes in the crossover. Someone has had the front cylinder off before as evidenced by the liberal application of orange RTV. Composite gaskets were used vs. aluminum on the rear cylinder. Cylinders and pistons look great - a light honing and new rings will be all that's necessary. No play in the rod bearings. Cam lobes look perfect. I did find the "smoking gun" though - where the ball came from - the cage of clutch side main bearing disintegrated and somehow one ball escaped. The inner race is quite damaged as well. The only other issue I've found thus far is stripped exhaust threads in the front head. It didn't help that the nut was cross-threaded into them. A tiny set screw was added in an effort to hold it all together.

Crazy on the call bearing, lucky nothing else got chewed up. Looks like maybe more than one ball is missing. Was the cage the metal type or nylon?

I think once they're all spaced correctly only one ball will be. Metal cage. Edit: 9 ball bearing, eight present, only one missing.

Finished tearing the engine down this evening. Found bits of the cage scattered around in the bottom of the engine cases. Lifters all look excellent. Rod bearings have a groove worn in the center, so while the crankshaft initially looked good, after a little measuring, I find that it will need to be ground.  :sad: Now if I could only find the dimensions somewhere - none listed in the factory Service Manual.  :shocked:

pretty typical failure on a early 350 engine , i had two of those failures , one on a engine with just over 10.000 km.
usually due to the sleeve on the crankshaft seizing, putting axial load on the ball bearing.
probably the reason they fitted a plain bearing on later engines.
I had good results with roller bearings on this application.
you might as well check the gear selector forks , on early engines they were anodised alloy , and prone to wear.

Yes, pretty much what I figure caused the failure. On the 3 1/2 Sport engine I rebuilt two years ago, I used an NU206ECJ/C3 roller bearing on the timing side and that's what the second 3 1/2 Sport and my Strada will both have as well.

Gear selector forks are steel.

Finished removing bits from the cases, giving them a good cleaning in the "dirty tank" first, then "clean tank" afterwards. Into the oven after that to warm the cases for easier bearing removal. My friend Mark (3 1/2 Sport owner) has offered to vapor blast the cases for me, so they'll go off to him. The cylinders and heads will be done at my local machine shop.

So, rather than have the stripped threads in the front head repaired, I bought another good used head on ebay. Cheaper than having the original repaired for sure. At some point, I'll have the original repaired to keep as a spare.


(https://i.ibb.co/R0rGJ0G/Morini-replacement-head-001.jpg) (https://ibb.co/R0rGJ0G)


Really glad I contacted the previous-previous owner, Roger. In addition to the bad news ("a ball came rolling out"), he found a box of what he had assumed was Guzzi parts, but turned out to be a bunch of missing parts from the Strada! The original side covers, airbox, headlight, Verlicchi throttle with cables, gauges, petcocks, speedo cable, headlight mount, horn and brake lever. Super happy to have all of it, but especially the sidecovers - they're a bit hard to find and expensive when you do. The headlight has been dented in the very back and pounded back out, but is usable as-is.

Why do most of the Moto Morini gauges seem to have the 'melted' needles? I haven't seen that on other Veglia gauges, did the Guzzi Veglia gauges use a better (stiffer or thicker) needle?

Just about the only source previously was North Leicester Motors. They closed up a year ago and sold all of their parts stock to Mdina. They're much easier to deal with - nice website with photos, it shows how many of each part is in stock, add it to your cart and pay with a credit card. No 10 % "US surcharge".

Came apart easier than I expected. Some bad news though: the steering stop on the frame is mangled and will need to be repaired, one fork tube has a kink in it that I can't see, only feel.

New headpipes (and exhaust nuts) are enroute from Italy now. The old ones would have cost a fortune to replate - lots of deep rust pits.

They are virtually indistinguishable from one another - same "color", just as smooth.

Last night I put the front brake disk in a cake pan and soaked it in EvapoRust. Morini brake disks are (hard) chrome plated, this one was pretty rusted in the center. Came out nice, but to keep it from rusting again, I'll paint the center and edge.

Cleaned up the rods, stuck the rod shells into them and checked the clearance with Plastigage. Falls right in the middle of the allowable range, so I'm good to go. Just need to buy new plugs for the oil galleries and install them, then I can begin engine reassembly. The old plugs were very reluctant to come out, so had to be drilled through and then removed with an easy-out.

Need to get all of the parts to be powdercoated  done soon, but before that can happen, the steering stop needs to be repaired or replaced and the sidestand straightened or replaced. The steering stop was mangled, then a bolt inserted as a (poor) "fix". I'm hoping it can be heated and formed back into shape, rather than cut off, a new one made and welded on.

Great thread Charlie!

Thanks for posting.  The gods definitely intervened on the behalf of that little bike by allowing you to get it instead of me.  With my limited knowledge, experience, capabilities, and sources, that thing wouldn't have seen the road ever again.

Looking forward to more posts.

Plugs for the crankshaft arrived from McMaster-Carr the other day - fit perfectly. As soon as I have a workspace empty, I can begin engine assembly.

Today I began reassembly of my customer Mark's 3 1/2 Sport (#2) engine - heating the cases and installing the bearings. Figured while the oven was warmed up and all of the bearings chilled, that I might as well do mine too.

Pulled the tank down off the shelf and remove the badges from it and the sidecovers so I could take some photos to send to the shop I'm thinking about using for paint this time. Pins apparently were broken off the badges (common) so they were stuck in place with some sort of adhesive.

A replacement (used) tank is the better part of $400, so I'm sending this one to a friend of a friend to be repaired.

Nothing to do but move on and try to get something done. Cleaning up the hardware to be sent off to be zinc-plated. Left bin are parts to be degreased, middle is parts needing to be wire brushed, right are finished ones. All done now, just need to box it up and send it off.

The painter I'm thinking of using will do the stripes in paint, same as the originals, only a little better. You can definitely tell they were applied by hand originally, perhaps after a bit too much vino.  :wink: I'm hoping the non-faded area behind the "3 1/2" sidecover badges will be sufficient for a good color match.

It's going to a "metal man" to have the perforated section cut out and new metal welded in. Soldering it would just be a "band-aid" fix IMO.

No photos this time around. I guess I could have taken some of the boxes ready to ship.  :wink:

Tank is off to Wisconsin to a friend of Mark's to be repaired. Hardware is off to Parker Metal Finishing in NC to be replated in "trivalent clear chromate", except for the voltage regulator cover which will be done in "trivalent yellow chromate". Box of bits stowed in the van to be dropped off at the powdercoater for wrinkle black. Once the frame repairs are finished, then I'll take it and the rest of the misc. chassis bits in. I can't decide between "Jet" (satin) or gloss. Leaning towards the latter.

The new headpipes and exhaust nuts I ordered on Dec. 15th are stuck somewhere in Post Italiane purgatory. Tracking shows them being in the same facility waiting to move to the next since Dec. 17th.  :sad: Marino Setti is doing his best to find out WTH is going on.

Edit: I guess the log jam finally broke free at Post Italiane. Tracking shows my parcel as being moved through Customs in NY! Finally! Moral of this story: don't order anything from Italy until well after the holidays.

Need to place another order with Mdina Italia (fork tubes and sprockets), but I'm having a hard to clicking on the "Place Order" button. My credit card screams every time I get ready to.  :grin:

Agreed.  I was curious since you mentioned using a sealant on a Gravely tank with pinholes in another thread that maybe there might be a magical fix out there somewhere that did not require surgery.

I'm sure some will swear by JB Weld, but that is also a band-aid.  When it comes to containing gasoline above a hot engine, fixing it right makes a lot of sense.  Solid metal is peace of mind.

I know the feeling.  If money wasn't involved, the project fun would never end.

That little bike won the lottery when you bought it.  No doubt you gave it more love and attention to detail than the Moto Morini production workers.

I figure my little Guzzi project bike is topping out at about $1400.  Not a bad price for a few giggles and a lot of fun.

If this was just going be some "rider quality" Morini, I'd would just seal it and forget it. But, this will be an almost complete restoration and I want it to be as well done as possible. I'll still be sealing the tank after the repairs have been made.

Very cool to see what can be done when one wants it "right!"

A friend recently bought a restored BMW for abut $12,000.  He said "I paid about $4,000 more than any other similar Beemer I have seen, but I know the guy who did the restoration, he does first class work, and I know he has about $25,000 into it!"

Sounds like the ultimate fun, if one has the funds or has customers who have the funds.

After vapour blasting and once I have finished assembling the engine / hub / etc... I wash down the exposed alloy with brake cleaner and then spray on a mist of ACF-50. I buy the ACF-50 in a 1 gallon bulk container (will last a life time) and pour it into a mister bottle, hand mist the part and then with a clean rag wipe it down. In a couple days I wipe down the part again and then just leave it. Once coated the part will resist oxidation for a very long time, probably good for a couple years of riding and washing.

Thanks Jim.  Good to know.  I have done the same with WD-40, Amsoil MP, or some of the gun spray oils.  Although it seems ACF-50 is the cat's meow!

I did not mean as a restoration, I meant on a bike that is still assembled, what would be your favorite cleaner?

I did not mean as a restoration, I meant on a bike that is still assembled, what would be your favorite cleaner?

If the engine is in the frame I have used a diluted solution of NAPA Aluminum Brighter, deadly stuff if not used with the appropriate safety gear but it will restore the aluminum to near original finish if you are patient. The Aluminum brighter is used to restore the bright finish on aluminum tanker trucks, manufacturers recommend a 25/1 mix ratio with water, I go anywhere 5/2 ~ 2/1 depending upon how awful the corrosion is. You must have a full face respirator with the proper acid cartridges and wear rubber gloves. Once you mist the surface of the aluminum it will foam up white as the oxidation is broken down then after a few minutes a high pressure wash is run over the engine, it takes anywhere between 5 and 10 passes of solution and high pressure but it will come out looking close to vapor blasting. Do this outside with a good high pressure wash wand. It will not hurt the paint but it will discolor anodizing so keep it off brake calipers! I have used this for many years and before I got a vapor blast cabinet it was my go to method of cleaning aluminum, engine cases, transmissions, wheel hubs, rims etc....

This Eldo engine sat outside in Florida for decades

My latest order from Mdina Italia arrived today. New fork tubes and sprockets. The sprockets are for 520 chain rather than the 530 that's stock. There's not much clearance for the chain in a few places, so the 530 chain needs to be the non-o-ring type. With a 520, there's plenty of clearance to run an o-ring chain. The rear sprocket is alloy - hopefully it doesn't wear out quickly. Weighs a lot less...

Do over. After I installed the left cover, I started on the clutch, first piece was the clutch basket. While installing it, I spun the main shaft - the starter ratchet was not disengaging, which meant that I had somehow installed it incorrectly. Back off with the cover, head scratching what I'd done wrong.

Fortunately, I recently bought an engine assembly manual done by the US importer of Morinis "back in the day", Herdan Corp. It's a bit easier to understand than the "blue book" factory manual. Once I followed the procedure in that and remounted the left cover, the starter worked like it should.

Installed the clutch basket again. "Back to square one."

Good move catching it then Charlie.  Never hurts to doubt oneself a little bit and double or triple check.  It's only time.

On the plus side you end up with some great stories to tell down the line, and the experience of making a mistake is invaluable, saves one lots of money and pain down the line....... but only if you are man enough to admit it!  Great thread!

What was the problem? Was it one of those engaging type roller bearings in backwards?

It's a kickstart assembly, so no "roller bearings" to mess with. For lack of better terminology, the issue was "timing" the ratchet so that it would retract properly. I don't know why I had a problem this time - I didn't when assembling the 3 1/2 Sport engine two years ago. Might be I was just too tired (I'm always working on my stuff at the end of the work day) and should have left it for when I was rested.

A bit of actual progress this evening. Cleaned, lightly greased and installed the "special washer" that goes between the clutch basket and hub.

(https://i.ibb.co/jknP0dJ/T3-engine-Morini-clutch-008.jpg) (https://ibb.co/jknP0dJ)


Cleaned the hub and installed it with a new locking washer and pushrod seal.

(https://i.ibb.co/ZNrCND5/T3-engine-Morini-clutch-009.jpg) (https://ibb.co/ZNrCND5)


Cleaned (I'm tired of cleaning!  :grin:) the clutch friction and metal plates and slipped them into place.

(https://i.ibb.co/8X81KnH/T3-engine-Morini-clutch-011.jpg) (https://ibb.co/8X81KnH)


Too tired to continue, plus it was time to get some supper. Just the pressure plate, springs, cups and nuts to go yet, then I'll be done on this side of the engine.

(https://i.ibb.co/YR8wKWR/Morini-clutch-2-V700-spot-mounts-001.jpg) (https://ibb.co/YR8wKWR)


Spent a little time wet sanding the clutch cover and then hand polishing it. It's not perfect, still a few scratches, but it's likely as shiny as when it left the factory.

Yes, almost complete rebuild - didn't need valve guides, so valves were refaced and seats touched up. I'll eventually be assembling the rest of the bike, the same as I did Mark's first 3 1/2 Sport.

Hoping to finish my engine sometime this week, now that the cylinders and heads have returned from the machine shop. Cylinders were cleaned and honed, heads had the guides replaced, seats recut and valves refaced. Frame and other chassis bits should be finished at the powdercoater late this week as well.

My next project is to strip down my 3 -1/2 motor, previous owner told me a petcock was left on and flooded a cylinder, starved the mains of oil, no idea yet if I will need to get oversize shell bearings and don't see them available on line at Made In Italy.

I was going to have the Strada's crank ground undersized until I found a good, used, standard-sized crank. Mdina Italia have 1st under shells available: https://www.mdinaitalia.co.uk/M250308.html

Thanks Charlie, I had missed that.

Thanks Charlie, I had missed that.

There's been some chatter on the MRC about the (aftermarket) oversized shells not being the same thickness as the (o.e.) factory originals. So, the shells need to be installed in the rods, the i.d. measured and the crank ground to fit.

Thanks for the heads up

I will take the crank and rods to the machinist I use for him to do his  magic.

After playing with the Sears/Puch way too much, I'm finally back to working on the Morini. Top-end reassembled today. Double checked the valve timing and found it spot-on.  :azn:

It's what I had on hand at the time, so I used it. Did need to elongate some of the holes so the bolts would go through.

The fan is actually quite modern - about 10 years old. I bought it because it looked vintage and instead of plastic, it's all stainless steel. I have the one my father built back in the '50s also - the base is the center of a truck wheel, motor is 3/4 hp, blade and guard both from an older fan that was scrapped. Sounds like an airplane coming in for a landing.  :grin:

A little more progress. Disassembled, cleaned and reassembled the intake manifolds with new gaskets and o-rings, after first flattening the gasket surfaces. Temporarily installed them on the engine along with the the rocker covers. The position of the manifolds will need to be determined once the engine and airbox are back in the frame and carbs installed. The rocker covers need to come off for them to be removed, plus the rocker covers need to be polished.

More done yesterday evening. Set the engine down off the table and put the frame up on it. Chased threads, removed powder from places it shouldn't have been, cleaned off the ground spots, etc.

(https://i.ibb.co/jkZ4Rjy/Morini-Strada-frame-prep-engine-installation-001.jpg) (https://ibb.co/jkZ4Rjy)


Installed two new centerstand bumpers. These are originally riveted into place, I used M4 button-heads, washers and nuts with a dab of thread locker.

(https://i.ibb.co/7KfGfk2/Morini-Strada-frame-prep-engine-installation-002.jpg) (https://ibb.co/7KfGfk2)


Then, it was frame off the table, engine back on, laid on the left side and blocked up level. The frame was then lowered down over it and the rear engine bolts slipped into place. One front engine mounting plate was loosely installed as well.

(https://i.ibb.co/R7HdycX/Morini-Strada-frame-prep-engine-installation-003.jpg) (https://ibb.co/R7HdycX)


Frame with engine turned upright for more assembly. Somebody forgot to order the extra thick washers and nylock nuts, so it's all on there loose until those arrive.

(https://i.ibb.co/ZB57VLC/Morini-assembly-001.jpg) (https://ibb.co/ZB57VLC)

Greased it up and installed new balls.

(https://i.ibb.co/dBwnqTm/Morini-assembly-007.jpg) (https://ibb.co/dBwnqTm)

Working on the gauges next. Cleaned and installed the reproduction gauge rubbers. Eventually, I plan to have both the tach and original speedometer rebuilt. This NOS "no name" Veglia speedometer will do for now.

Reusing the original Marzocchis. I've ordered rebuild kits, but they're coming from Italy, so could take a while. Neither damper is leaking and both have good damping for the full stroke, so I might just give them a paint job and leave it at that. The springs and retainers are off at the chrome plater now.

Everything fits pretty well. Glad I bought the later style Grimeca master cylinder rather than finding an original one though. The outlet of this one is on the underside, pointing down. The original is straight out the end and can make hose routing "interesting".

Mixed weather day today, so instead of going riding, I decided to try and make significant progress. Achieved my goal of getting the front wheel on.

After lots of cleaning, the wheel looks pretty good, especially considering it's 43 year old paint. A chip here, a scratch there - no biggie - there will be more. Warmed it on the burner of my stove, so that I could install the new bearings.

On to the rear wheel...

Modified an old carriage bolt to work as a puller (along with a socket) to remove one bearing and the central spacer. The other bearing I drove out once the metal ring was removed.

(https://i.ibb.co/7QJkHst/Morini-rear-wheel-1-003.jpg) (https://ibb.co/7QJkHst)


New bearings and central spacer. The design of the central spacer makes it a bit harder than normal to remove the bearings.

But, the bearings are out and that's all that matters.

Squeezed in another work session today. Installed the wheel bearings - heated the wheel on the stove, chilled the bearings in the freezer over night, after installing the central spacer into one of them. First bearing with spacer tapped into place with some Delrin tube and a small hammer. The tool I made to remove the bearings doubles as an installer as well. Set the second bearing into place, slip the bolt through, slip on a washer and nut, tighten. Seats the bearing into place perfectly.

Almost on it's own two wheels. Right now only the front and centerstand. Need to get the shocks done before it's a roller. Now that I have the rebuild kits, I can rebuild the dampers (or not - they're not leaking and have very good damping for the entire stroke). Springs and retainers should be returning from the chrome plater in the next few days.

Disassembled one rear shock today. I was figuring it would put up a fight, but for once, something went easy. The paint was literally washing off while I was cleaning it up.

While I was cleaning up my spare airbox before sending it to Lloyd/r1100purist, I decided to just do the one for the Strada as well.

(https://i.ibb.co/k6KVN3Q/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/k6KVN3Q)

Cleaned up pretty nicely. Missing one nut. Installed the new air filters while I was at it.

My chrome finally returned from Frankford Plating in Philly. They did an excellent job, but one piece I sent didn't return (the "washer" that fits on top of the kickstart lever). Hopefully they just forgot to pack it and didn't lose it. If they lost it, I'll make one out of stainless steel.

Loving that original finish on the wheels. My first moped, when I lived in Italy in the 80's was a Malaguti Gabbiano and had that same finish, probably same factory made them. I spent a lot of time cleaning them, so pretty familiar with them up close. A finish you want to sink your teeth in, but maybe that's just me  :azn:

I finished up two customer projects yesterday, so today cleaned up the mess I made in the process, and then rearranged things a bit. The Morini went from the center of the shop to the back, on Lift #1. Spent a little time this evening remembering how the shift linkage all went together and taking notes of what hardware I lacked. It's all together, but with stainless bolts and I want grade 8.8 for this application.

I could have saved myself a lot of time if I had taken a few notes and more photos during disassembly. The US mandated left-side shift adds a bit of complexity and I found myself wondering why I didn't just find a right-foot shift setup.

Fiddled with the brake side as well, just putting the pedal into place and accessing the condition of the cable. The cable is in very good condition, just a bit "cosmetically challenged".

The axle adjusters are fully aft and it's nowhere near tight, so I think it needs two more links off of it yet. At least I didn't cut it too short.  :grin:

Finished up the chain - removed two links and carefully adjusted the chain.

(https://i.ibb.co/9cNBShr/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/9cNBShr)


Morinis have no marks or anything, so you need to figure out some way of checking alignment. I use the laser of my infrared thermometer. Place the top of the thermometer against the rear sprocket, pull the trigger and see where the dot points to on the countershaft sprocket.

(https://i.ibb.co/hRkv3Kb/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/hRkv3Kb)


The laser is 8 mm from the face of the rear sprocket, so I aligned it so that the dot was 8 mm from the face of the countershaft sprocket.

(https://i.ibb.co/c3dBd4j/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/c3dBd4j)


Tension correct, so the right engine cover is temporarily refitted again.

(https://i.ibb.co/bvTCmzZ/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/bvTCmzZ)


Next up, I cleaned the brake cable and installed it.

(https://i.ibb.co/QmrrZqN/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/QmrrZqN)


Something isn't quite right here - the adjuster is the whole way out for the pedal travel to be close to correct. It was this way before I disassembled the bike too. Brake linings are approx. 5 mm thick, so still usable. The cable just seems a bit too long. I might make up a spacer to take up some of the cable length.

I had a little time to spare this evening, since no mowing the yard, due to rain. Got the ladder and fetched the big Motostoriche Italian box from high up on the shelf where I stuck it shortly after it arrived back in February(?). Collected all the misc. bits together - half rings, gasket and new header nuts. The header pipes are well made - double wall, nice bends and chrome - but the crossover fits loosely onto the stubs. Too large of inner diameter and no cuts at the ends so the clamps can even have an hope of compressing it enough. So, I made three cuts (somewhat) evenly spaced. Gave the pipes and clamps and good coat of wax and then set about installing it all. The half-rings are fussy to hold into place during assembly, so I stuck them into place with Permatex Ultra Black RTV. Same with the gaskets. Threads were coated with copper anti-seize. Installed the left/rear cylinder pipe first.

(https://i.ibb.co/cQmWm5R/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/cQmWm5R)


Applied Ultra Black to the stubs and inside the ends of the crossover and slipped it into place. Then the right/front cylinder header attached to the head and rotated down so the stub went into the crossover.

(https://i.ibb.co/tpcgFFP/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/tpcgFFP)

Hi Antietam.
Your rear brake cable?, welcome to the world of Morini parts! hehe!. I can think of at least three different lengths of cable, and I think that's before we get to the ones for rear set footrests, and crossover conversions. On one of my sports I had to relocate the brake lever on the drum to get it to work. Stewart at NLM used to know which one to use by just telling him what set up you had. I'll bet there's one specifically for the crossover conversion?. Try a post on the Morini forum?.
Good luck, wonderful little bikes!.

The rear brake cable is the one the bike came from the factory with as far as I know. The arm has already been rotated another spline to make it work and I added some slip on extensions at both anchor points. Works fine now, but I don't really like using the extensions. I'll either make a single, longer extension fitting or just alter (shorten) the cable to fit better. No biggie.

I suggest letting it leak out all its oil and then mount it for aesthetic purposes. It looks the biz but is unnecessary, and when these dampers actually work, they cause the mounting bracket to bend and eventually break.

The US seems to be the only market where Stradas were actually fitted with steering dampers in the first place. I won't be mounting it "for aesthetic purposes" - if it doesn't function, then it will be replaced or removed entirely.

A few photos from the other day I forgot to post. I was working up an order to McMaster-Carr and remembered I needed side cover knobs. Pulled the sidecovers out and measured the maximum diameter that would fit without interfering. That done, I put the new rubber isolators on the frame prongs and hung the sidecovers just for the heck of it.

Probably should have went out for a ride since it was ~ 60 degrees and the weatherguessers are calling for a foot of snow on Wednesday. But, I felt the need to get a little more done on the Morini instead. It's time on the back lift is nearing an end for a while, so I wanted to complete a few tasks that wouldn't be as easily done on the floor.

First up was to install the ignition pickup. That ended abruptly though - the sheathing for the wires was hard and cracked, and I don't have a piece 36" long. Put that on my list...

Moved on to installing the alternator stator. This went well and before I remembered to take a photo, the flywheel was back on.  :wink:

Nice work finishing the spaghetti junction!  At first I thought the Moto Morini approach to wiring, individual wire components instead of a single bundle, was awkward. I now think Moriniís method is superior for troubleshooting and replacement. Looks like you are close to being able to fire it up.

Ignition pickup, plug wires, carbs, and throttle cables, then I can run it from a bottle. The tank needs lots of "love" - rusty inside, one dent. Need to save up enough $$ (not spend any on Pantah) to have the bodywork and paint done.

If you need any ignition bits my 500 Morini has been swapped to a Sasche coil ignition, the original transducers and cam pickup are redundant to me, PM me if you can use them. I have kept the stator for charging the battery. Good luck with the tank, I hate rust! I am using diluted muriatic acid these days to attack stubborn rust but its serious crap and the usual precautions from breathing the fumes are essential.
Looking forward to your startup report!

Sending you a PM regarding the ignition bits. The rust won't be too difficult - diluted milkstone remover (available from Tractor Supply here) will make short work of it. IIRC, it's main ingredient is phosphoric acid.

Carburetor cleaning today! Now my clothes stink of old gas and carb cleaner... Not terrible, but a good coating of tar-like goo and brown fluffy crud. "Only" five hours later they're clean and ready to install. With all of the bits I had replated, they really look nice. The bowls were a bit corroded, so I wet sanded and polished them.

Manifold installation today. First, removed the rocker cover so that the assembled manifold can be rotated. Installed the carb and rotated it into the correct position.   

(https://i.ibb.co/Lg7tKGH/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/Lg7tKGH)

This is where it gets "fun". On the last engine I did, I just applied thread locker, positioned the manifold where I wanted it and ran the lock ring down to secure it. But, that leaves a gap between the end of the manifold and the cylinder head. This time, I decided to use a crush washer to fill the gap. The problem is, I calculated that I would need a 1.3 mm thick crush washer on the left, and a 1.05 mm thick one on the right. Plus, the crush washers I have on hand would need the inner diameter opened up (besides being thinned). To thin them down, I made a plastic holder and then rubbed them back and forth on a file. To open up the i.d., I used a small oval-section file. As you can imagine, this took a while. But, I got it done.

Crush washer down in the port.
(https://i.ibb.co/t2RyBVt/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/t2RyBVt)

Installed the manifold again, tightened it down against the crush washer - perfect! Mark the position.
(https://i.ibb.co/YbsZMsG/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/YbsZMsG)

Apply thread locker, thread in until the marks align, spin the lock ring down and tighten.
(https://i.ibb.co/dgjpJhs/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/dgjpJhs)

I would have the throttle twistgrip and cables on if the new cables actually fit. Free length is approx. 8 mm too short. It seems that Venhill can never make a cable correctly...  :sad: I need to source or another pair, or I may just send the originals to Barnett and have them make duplicates.

These are notoriously difficult to find and I was fearing a lengthy wait before I could find one and get the bike running (soon). Then I remembered that my Ducati uses the same switch/throttle assembly as the later electric start Morinis. Could it be the same as the one for the metal bodied, no switch throttle? Yes, yes it is.  :azn:

About 8 years ago one of my sons had the V7 Sport headlight plastic socket made for me with 3D printing, he hand built the mesh measuring the original with a micrometer. Those days of detailed input are a thing of the past, now a full detail 3D scan can be taken with your smart phone and send the mesh to a 3D printer over the web in munites.
Autodesk was a leader with '123D Catch' but they dropped the program, Scandy Pro is a newer piece of software you download onto your smart phone to take a 3D scan, remarkable tech for dirt cheap. Ten years ago the tech to accomploish this would have cost tens of thousands of dollars and taken umpteen hours to build.

https://www.youtube.com/watch?v=91HX5gep-I8

I am going to get scans done of the Morini stator coil spools.

The things that can be scanned and printed is unlimited, think about those pesky LeMans switches that go for stupid money in beat up condition!

The Morini system is Ducati Electronica and as far as I know is only used on Morinis. My Pantah (in another build thread) has the same Bosch system as a V50 II. Canuck750 (Jim) sent me a complete system off his 500 for the Morini and I have spares for the Pantah already. Thanks for the generous offer though.

Here's something you likely never saw.  A 3 1/2 with a sidecar bolted to it.  Kind of like hooking a race horse to a plow.  A friend got a new Morini for almost nothing and built a side car to match in.  Spent time in my garage till the kids got too big for it.

Seven months since I last accomplished anything. That changed today. Rainy day, so I stayed home and worked.

First up: retension the kickstart spring. I thought I had it right, but the lever wouldn't return. This time I followed the procedure in Paul Compton's video.

Going back together. Lever returns nicely now.

That job (re)done, moving on to the ignition. New sheathing on the pickup wires, pickup installed along with the later style rotor that Canuck750 sent me. Connected at the transducers.

A little more progress this evening. Modified the (not the greatest quality reproduction) gauge rubber mount so that the (non-original) speedometer that I'm using temporarily fits better. Just used the little drum sander in the Dremel to make a few notches.

(https://i.ibb.co/sRzG2H3/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/sRzG2H3)


The speedo is a n.o.s. unit I bought years ago. I don't want to remove the mounting studs since it's not permanent. The original works, but the needle is warped and rubs on the inside of the glass.

There's supposed to be a metal piece that is shaped like and fits over this rubber vibration isolator. Despite my best efforts, I never was able to find a pair, so will likely make some from stainless sheet.

For now, a fender washer does the job well enough.

Rethreaded the other stem and installed the right signal.

Need to make longer signal wires so that they can be tucked under the taillight bracket.

Wouldn't matter too much with the long dual-seat, but they're exposed with the Sport seat.

Stuck the bodywork on to see how it looks. Tank and sidecovers still need to go off for dent removal and paint.

I have a replacement seat cover from the original manufacturer of the seat. Anyone following will have no doubt what's ahead of them.  :laugh:

That explains it.
I was going to ask how you printed on the seat cover.  :smiley:

No, back to the same (original) color and pinstriping that's on it now.

good choice, I would probably do the same and keep it original :thumb:

A few "milestones" reached.

My friend Robb gave me a set of plug wires originally meant for his Kawasaki KZ1000 but never installed.

(https://i.ibb.co/qpWmhrN/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/qpWmhrN)

One made both plugs wires. And spark!
(https://i.ibb.co/RTFv4Bt/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/RTFv4Bt)

Tied up the wiring on both sides around the steering head.

Ran the rocker breather hoses.
(https://i.ibb.co/hDRkGgB/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/hDRkGgB)

I'm not happy with this main breather hose, so will be replacing it with one a bit more flexible.
(https://i.ibb.co/k2m1FhB/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/k2m1FhB)

Battery installed. The first electrical test didn't go well - nothing worked except for the light that meant the key was on.
(https://i.ibb.co/JRY5mdS/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/JRY5mdS)

Then I remembered I hadn't installed any fuses yet! Once the fuses were in place, everything worked.
(https://i.ibb.co/GvGzhdj/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/GvGzhdj)


Thinking ahead. I bought these mirrors for the V50, but could never see anything due to the short handlebars. I think they will work on the Morini.

(https://i.ibb.co/QXLdZVd/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/QXLdZVd)


They came with a nice handlebar mount that almost perfectly matches the master cylinder clamp.

Only a few minutes to work this evening. Did get the wires tucked away under the taillight.

My electronic flasher arrived this afternoon. I made a little extender for it's mounting clip to move it down about an inch.

(https://i.ibb.co/xsg4cXv/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/xsg4cXv)


Taking photos of the bodywork again, for another prospective painter. I buffed out the area under the 3 1/2 badge on one sidecover and I think it's about as close to the true original color as I'll get.

(https://i.ibb.co/PG1V1wV/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/PG1V1wV) (https://i.ibb.co/87S0W9y/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/87S0W9y)

The right side of the tank doesn't look too bad other than the dent.

Not terribly rusty inside.
(https://i.ibb.co/7kR8VVJ/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/7kR8VVJ)

But, the left side had a bunch of pinholes that I had welded up. Decided it would be best to leave smoothing them out to the bodyman.

On to the seats. The original dual seat is apparently a bit of an odd-ball - when I contacted the original manufacturer (Nisa in Italy) about a replacement cover, they wanted to sell me one about 30 mm too short. They seem to have no record of longer ones being made, but this was definitely factory. Removed the tattered remains of the original cover.

(https://i.ibb.co/hFSkQ41/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/hFSkQ41)


Found this shrunken red piece of plastic, not sure of it's purpose.

(https://i.ibb.co/TDXMXSH/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/TDXMXSH)


The foam is pretty stuck to the pan. You can see the extra section added.

(https://i.ibb.co/sCHGXqY/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/sCHGXqY)


The pan is solid other than a small crack at the center hole.

Photos for Nisa, since they don't seem to believe me.

If they can't supply a cover of the proper length, then I'll have my local upholstery guy make a copy of the original.

Next up, the solo seat that canuck750 gave me. It could be used as-is, but the cover isn't quite right, so should be re-covered.

(https://i.ibb.co/k9nxv08/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/k9nxv08)


Drilled the heads off all of the pop rivets securing the cover.

(https://i.ibb.co/4RK0qyt/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/4RK0qyt)


After a bit of a fight, the cover came off. It was glued on, with thin foam over the original foam.

(https://i.ibb.co/FmQ1SPS/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/FmQ1SPS)


Lovely pink edge trim.

(https://i.ibb.co/NsV0Xmp/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/NsV0Xmp)

(https://i.ibb.co/9WxfHjK/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/9WxfHjK)


And reusable foam.

(https://i.ibb.co/6FK5qHs/OLYMPUS-DIGITAL-CAMERA.jpg) (https://ibb.co/6FK5qHs)


Need to decide whether to have the pan powder coated and new cover installed, or not. To make it complete, I'd still need to source the aluminum trim, screws, nuts and washer that are missing. The cost of it all is probably more than a new (made by Nisa) seat. Need to sleep on it.

I dropped the seat pans off at my local powder coater for sandblasting last Thursday and picked them up today. The Sport pan is in very good condition with just a crack at one hole on the side. The dual-seat pan has the same crack in the same place, plus a little perforation at the left rear. Not too bad for their age.

My customer Mark (who owns three drum-brake 3 1/2 Sports), recently purchased an early Strada as well. It came with a spare later style tank in lovely red paint, and he's agreed to sell it to me. It will be a much better starting point than my original. There's one dent in the top, but otherwise it's solid and leak-free.
