Title: V7 Sport (road rash)
Post by: czakky82 on November 27, 2021, 09:20:48 AM
Looks like my last attempt to document my rebuild was deleted.
Iíll try again.
Frame is stripped and Iíve got both engines pre-inspected now. Iíve all but decided to run the original engine.

Now for the bad newsÖ looks like the frame is tweaked a bit. At least I think it is. It wonít sit flat, the left front is about 2mm off the ground. Is this a lot? Itís not detectable by sighting it down anywhere.

2mm may not be that significant, depending upon the reason.  Is one of the down tubes bent, neck twisted, ? or is the lug at the bottom of the tube  The lower frame rails bolt in place and it isn't a press or precision fit.  Have you bolted the lowers in place to see how all aligns at that point?
 
I understand these frames are prone to cracking where the bottom of the front down tubes attach to the lugs.   If the 2mm doesn't pull the frame out of shape when lowers are installed and tightened, that's lots better than having to have cracks properly serviced.  One of my down tubes was welded/repaired & not pretty when I got the bike.  I've never fixed the repair.  Maybe someday.

Good points. The lower rails were loosely bolted up originally. I put them into place and the left side lined up perfect. The right side was close but not perfect. I was able to get everything bolted up no problem but the holes didnít line up absolutely perfect on that side.
Iím leaning towards running it as is.

Engine stripped and getting ready for vapor honing.

The head and cylinder are empty, Iím not using either the heads or cylinders just there to protect the mating surfaces. Probably unnecessary but Iím trying to seal it up somewhat to make clean up easier.

Crank is going to the machine shop to see if it will polish up.

Rod bearings and main bearings are pretty rough.

Vapour honing will not damage mating surfaces, it is safe on aluminum, steel, brass and most plastic. The glass media / water slurry is very gentle but it gets through the thinnest joints so better to send parts completely disassembled into individual pieces for vapour honing.

Shells and mains look pretty worn. Have you measured the crank bearing surfaces to determine if you will need a regrind and oversized shells and bearings? Every non filter GUZZI big twin I have rebuilt needed oversized bearings, damn chrome flakes and poorly filtered oil causes all kinds of grief. Looking at those bearings I would expect the oil pump to be worn out as well.

Glad to see you saving a rare bike! 👍

Sounds like I can get by without protecting the mating surfaces with vapor honing. Can threads get damaged?

I havenít had the crank measured yet. Fingers crossed I can get away with just fresh bearings.
A fresh oil pump is in the budget.

Vapour honing will not damage threads but blind holes can be hard to clear of media, when I can, I thread in an old bolt into the threaded hole before I vapour hone. Regardless of plugging holes or not, I chase out all threaded holes before reassembly.
Vapour honing with fine glass bead is very safe, the bead does not fracture on impact like dry blast so no tiny shards of glass bead get embedded in the porous surface of the casting. I pull all ball bearings and races out of all castings before blasting, near impossible to get the media out of a bearing. After honing I rinse and with compressed air blow dry the part then rinse and dry again. After you finish assembling the engine spray it down with brake cleaner followed with a spray and wipe of ACF-50.
Vapour honing only pulls off oxidation, it does not damage the base metal.

Post by: Scout63 on December 12, 2021, 10:16:03 PM
Czakky you should expect to run a tap through every threaded hole in the case as the media will soften up threads.  Especially vulnerable are the front timing chest and sump holes and the cylinder head rocker cover screw holes.  The result is so worth it though. More pictures please.

I understand that people prefer not to have to turn these crankshafts, but do what you need to do and move forward.  If it needs turning, it doesn't look like it will need much.  Glad to see it's not badly gouged or grooved.  fwiw, my crankshaft had to be turned, so it was.  Many happy trouble-free miles since...

Post by: czakky82 on December 13, 2021, 07:29:36 AM
@Canuck, I think I will go through with my original plan to seal up the cases. Should be less clean up when done I hope. I think the trans should be pretty well sealed up hopefully saving me from having to replace all the blind bearings insideÖ?

@Cliffrod: I keep going back and forth between fitting an oil filter conversion or notÖ Maybe I can see what the machine shop will charge for drilling.

Other news, it looks like Iíve got an 850t rear drive with a slightly shorter gear ratio that Iíll be using.
Title: Re: V7 Sport (road rash)
Post by: Canuck750 on December 13, 2021, 08:51:12 AM
I have been asked by many folks to vapour hone their motorcycle parts for them and regularly do so. Some folks have asked to try and blast parts with blind bearing and races left in, carefully blanking off all openings. In every case the media found itís way in. The blast cabinet runs at 90 psi pressure, trust me the slurry finds its way in. If you blast the transmission case you have to get the bearings out of the case, there is space, tiny as it is, under the bearing races. I have had my Vapour Honing cabinet for over five years now and it gets used most every day, it takes a little prep work but it is worth it.
The Vapour Honing process will not remove paint unless there is corrosion under the surface and it does not like grease or dirt, parts need to be washed before blasting.

Cleaning very thoroughly is super important no matter the method or media. The last Morini 3 1/2 engine build I did for a customer had been vapor blasted by him and media was packed in bolt holes and crevices like concrete. Very hard to remove - for M6 bolt holes I ended up using a .22 caliber rifle cleaning brush!

Not all dry blasting machines are created equal. The machine shop that cleans my cases has a shot peening machine made by Blast-It-All which they run at 15 psi. The blast media (Potters Ballotini) does not fracture at such low pressure so there is zero chance of any of it being embedded. They plug all bolt holes and oil galleries, mask most gasket surfaces and clean the part three times.

Engine and trans cases back from vapor blast. They turned out really nice. Iíve been cleaning gasket surfaces and chasing all threads with a tap. I will clean everything out with brake cleaner tomorrow give it wash in the slop sink and blow dry with compressed air. Iím waiting on the verdict on my crank at the machine shop. Then MG cycle will have a big order headed there way.
Im on the look out for a good stainless hardware set when Iím ready for assembly.

Before I start reassembling the trans on this bike Iíd like opinions on condition. Iím going to replace any dogs available and bearings. Sorry my photos arenít great.

Powder coater called and said my parts were ready :drool:. Iíll be able to pick them up on Monday.

In the meantime Iíve got a shipment coming from HMB on its way with a bunch of cool parts that will get me closer to completing my engine.

Heads are at the machine shop along with my crank and rods. There was basically no good news. From wrist pin bushings down to the crank everything must be re-ground. They are going 1st under on the crank and fabbing up new small end bushingsÖ. Also, k-lining valve guides. 1st under rear mains are nowhere to be found so they are going to give the 2nd under acquired from Harpers a haircut.

In the meantime Iíll be rebuilding the trans with all new bearings, seals and gaskets.

Iíve got a question about the console color. What color is a good match for the gauge surround and idiot light holder?

Thanks for any input

Bearings are seated all the way Iíve tried both ways with the steering lock. Iíve got all parts installed from the schematic.

Is that the way these are?

On the other hand the wrinkle paint turned out pretty good. I used it on the top triple and ears. I just went satin black on the console and gauge surround, then I went ahead and broke one of the lensesÖ
Anyway once my crank is finished I can start really boogying on this thing. The crank guy has been puttzing. Iím a little concerned, weíll seeÖ

Post by: czakky82 on March 20, 2022, 06:51:30 AM
After getting the front main bearing re-sized progress can begin again. One cool thing Iím doing is adding an HMB oil filter system. I never mind dropping the lower sump on Guzzis, in fact I kind of like getting a thorough oil change. What I really like about this system is that for roughly $300 you get a sump spacer, filter, pressure relief, and an easy access oil filter. I also went with HMBs mid range cam and there oil pump. Doing a shade tree measure on the cam it looks to have about 1mm more lift and probably slightly more duration a bit earlier in the rotation. HMBs stuff looks really good, all billet well made stuff. Micheal is super easy to communicate with via e-mail. I know folks have complained about there packaging methods but Iíve had a couple of big orders with them and can say everything has been well packaged. I honestly wish I wouldíve bought more from of my parts from them but shipping is a killer from Germany.
 I will also have one of Edís light flywheels too. Thatís all for go fast stuff.
Anyway oil pump, cam, crank installed. Then onto the filter sump parts. It all went fairly easily. I might try to knock some sheen off the sump spacer part as it stands out quite a bit right now. Weíll see.

Progress once again halted. It looks like the inner cylinder studs were shortened for the dual plug conversion this bike had originally. I found some on eBay, so not a huge deal.
I have dry fitted my timing gears and noticed that the cam gear has only .006Ē clearance from the front bearing flange top two bolts. The only thing Iím doing different is using schnoor (sic?) washers. I guess Iíll have to use the bent piece of tin for those two. Iím not sure if the new flange is thicker. Iíll re-assemble and measure. Iím just not comfortable with it being that tight. The HMB oil pump puts the pump gear close to the case as well. That might promote more oil to the gears actuallyÖ

Then the situation has changed drastically, probably because of complaints, damaged and lost parts. I've had cylinder sets arrive in just their thin fitted boxes that were loose in a much larger box with zero bubble wrap or any other packing material. I got lucky and nothing was damaged, others less so.

I remember reading complaints about that and of course it influenced my decision to do business with them but in the end I ended up spending money with them obviously. A couple years ago I bought some discs for (now Tomís) a T3. It was pretty poorly packaged but they arrived intact. I think they do some really neat things there and Iíd like to support them if possible.

Transmission rebuilt using the guts bought from the swap meet. Cali 1100 I believe. Same gear ratios, an extra o-ring here and there. Every bearing besides the internal thin rollers on the shaft(s) replaced. Drum shimmed, Prussian blue on the ends of floating shafts to verify they are not making contact. Final assembly and it wouldnít shift out of neutralÖ. :embarassed:, disassembled, I found nothing. I re-assembled and it shifted great. I have no idea why.
I managed to fit the clutch and starter ring tonight, forgetting where I had that old deep spline input hub. I was able to line everything up without it. So the most complex and expensive parts are done.
Iíll try to take more pics now that the operation is moving out to the shed from the basement.
The output seal on the trans is a bit proud of the speedo drive. I remember when rebuilding Tomís T3 it was the same. I even ordered another seal thinking I mightíve installed the wrong one, I didnít. Anyway this seal was a bit different and looks to do the same thing. The T3 didnít leak so hopefully this one doesnítÖ

Progress is progress but, Iím light on pics.
Some wiring done and I made a decision on foot controls. My options for now are either: cutdown v7 brackets and fabbing 850t shifter/rear brake linkages to work, run the cut down ďdownstairs mixupĒ controls (wrong side, right way up) or what Iíve decided 850t stuff all around until I can get my grubby paws on some v7 sport footpegs. Itís something like 40mm forward and down from V7 sports.
I also decided to re-seal the rear drive. It took some clean up on the two seal surfaces. It should go back together tomorrow. First time that deep in a Guzzi rear drive. I think I could handle a gear swap if I needed. In other words a shaved ape can take it apartÖ
Antietam CC gave me some (offline) advice on rear hub casting issues after I made a snap judgment on some ominous looking flaws in the rear hub. Turns out I was fine! So that should go back together soon too.
Tires, exhaust, footpegs and a good headlight are the major purchases due.

For a headlight look on German EBay for a Moto Morini 3-1/2 headlight, my 1975 3-1/2 headlight is identical to the V7 Sport, if you can find one it will probably be much cheaper than a V7 sport headlight, the Benelli 650S also uses the same headlight, earlier 650S is similar except for the 4 prong wire terminal plugs are individual rather than being on a common plastic receptacle like the Sport unit and the shell will be painted black rather than chrome.

Post by: Canuck750 on May 07, 2022, 10:17:27 PM
Detlef Burian, the Benelli parts guy in Germany has the correct headlight used for 160 Euro and new for 230 Euro, check his website, look at the Benelli 650S page and scroll to the electric page, click on the headlight and the prices pop up on top left of page

https://www.benelliparts.de/

You will need to check if the headlight shell is black or chrome, they were typically black on the Benelli

TLM has the headlight ears in stock

850T tool boxes use the same back setcion, Moto Guzzi Classics used to sell repop fiberglass V7 Sport lids that you can rivet to the original steel hinges on the T box, check with Mark to see if he has any lids

Some big and little wins the last few days. After realizing I had my ignition timing a few * outÖ It fired up in half a crank! Iíve got to sort the idle,etc but thatís huge for me.
Also after a few weeks of soaking in penetrating oil the fuel solenoid freed up. I always thought this to be a cool (slightly silly) feature and wanted to use it.
The little cable splitter for the Magura throttle that was graciously recommended by Antietam CC showed as being sold out right after I ordered it and I never got a shipping confirmation so I sorta assumed I was outta luck. I was super happy to see that package show up today! I also dig the Uber simple, ratio-less original throttle. Combined with the VHB slide springs, this throttle and the fresh clutch springs this bike might test my manhood. :embarrassed:

Hereís my attempt at sharing a video. Yes grammar bad, carbs are far from synced (cable splitter hadnít arrived at the time)

My wife, who was filming was apparently not impressed, as she immediately asked what I wanted for dinnerÖ

I am getting closer to finishing what I aimed to accomplish on this bike for the summer.
I have put 200 miles on it so far, atleast 10 heat cycles, re-torqued heads 3 times (last time seemed pointless) but Iíll do it twice more at a minimum, Iíve gone through the jetting using my butt dyno. I arrived at 50pilots between 1.25 turns left, 1.5 right, V9(?) needle at richest, 40 slides, 135 mains. This has a lightened flywheel and the HMB V7 Sport cam. Some cool looking velocity stacks originally off of a Ducati single and classic Uni sock filters ill fittedÖ.
I havenít brought it to redline yet as Iíll wait until I change the oil again in another 300 miles or so.
Carb syncÖ.
No vacuum ports on these manifolds. I was thinking about trying this method.

Seems a little hard on the coils? Opinions?

Iíll post some pics when I get the exhaust mounted.

With any luck I will get the tins painted this summer, otherwise Iím mostly done. Lots of adjustments, possibly an electronic ignition at some point.

I still have that set of original V7 Sport 'stacks if you want them.

I'd either sync the carbs by measuring the slide opening(s) with drill bits, or just drilling and tapping the manifolds for vacuum fittings.

Looks great!

Thanks guys! Iím not on Dave, Antietam, or Canuckís level by a long shot, but itís fun.

Iíll send you an email on those stacks in a while. Iím traveling a bit the next few weeks.

Iíve got a few hundred miles on the old girl now and have been able to open it up a bit. So I thought Iíd give my riding impressions.
Iíve owned three Guzzis in my life. A long term, oft crashed, bastardized, v11 Sport since sold. A lightly modded, mechanically refreshed T3, now owned by Tkelly.  :cry: I do miss a bitÖ In good hands though.
Now this.
The most noticeable thing about a V7 Sport right away is how tall the gearing is. Most bikes from this period and beyond I find myself searching for a 7th or 6th gear that doesnít exist when first riding. The v7 I was looking for gear below 1st! One of the first few rides I was thinking about how tall the gearing was going down the highway at 70mph, until I realized I was in 4th! I mean indicated 80mph is the only time you need be snicking into 5th!
The next noticeable (read:charm) part is the honking 4ls drum. So sexy to my eyes! My dad was only 12 when these were new but somehow Iím (at 40) nostalgic for the times of big mechanical brakes. These are honestly better than expected. I had a pretty worked over Yamaha that sported an XS1 2ls brake stopping a wild RD350 thing I built and it totally stunk if honest. This 4ls is almost adequate and Iím still fine tuning it a bit. Iím obviously not going to outbreak any modern bike but if youíre able to give it a healthy squeeze itíll slow you down. It also doesnít overheat as easily as I thought it would.
The engine is mostly stock save an HMB home brew camshaft and a pro lightened flywheel. Iíd like to add a Sachse iggy and eventually have heads ported properly and add 32mm carbs. Not today though. Compared to Tkellyís T3 it doesnít have a ton more power maybe 3-4 more Hp, and likely less torque especially with the higher gearing it feels that way. It does have such a cool sound with the Lafranconi Competizione mufflers and short stroke itís amazing! Power builds more so with this engine than the T3 as well. I havenít been up over 6500rpm yet but it has no tell of signing off.
I really spent some time on this transmission when rebuilding, replacing almost all bearings and spending a TON of time on shimming the shift drum within a gnats bum. I sourced a solid heim joint linkage for my basically 850T foot controls and think I can dial this in more. It still shift like a Guzzi, which is uhh charmingÖ better, but you still canít be careless when shifting. Getting the perfect Ďsnickí into gear still requires some care.
The riding position (with 850T foot controls) is not bad. Aggressive enough that nobody is going to confuse you for a cruiser and the IMO perpetually disconnected front end of a Guzzi has more feel with the repro swan necks. Keep in mind this front wheel weighs a TON! However the fork dampers are pretty shot. Tkellyís T3 has renewed dampers and springs, disc brakes, etc. and is much more compliant. Iím thinking Iíll have some FACs(?) relatively soon. The rear Koni shocks, surprisingly good after a rebuild! If I can swing the cost of re-chroming the springs Iíll be happy!
I canít remember what clutch I went with, itís fine. You gotta be serious about using it, no wrist relief here! The good part is once in 3rd you donít need to use it much while strafing corners with the tall gearing.
I still hope to get the tank and toolboxes painted this summer and use the original broken footpegs to fab a more closer to v7 sport foot controls.

All in all, an involved machine that makes you feel cool when you ride it!
Thanks for indulging me :bike-037:

Congrats...really interesting to read your road report .
I've thought about building a short stroke engine for a long time...
