Title: Refurbing my v65 SP (was '77 T3)
Post by: egschade on June 29, 2022, 06:57:02 AM
Considering this T3 near Trenton, NJ and would like a little feedback. I believe that 77's came stock with chrome bores so I asked the owner if they've ever been replaced. Anything else I should ask about?

Bub sump seems to be working OK. Looks fine to me. Says he did top end work. Ask.

Looks pretty good to me, unless the chrome bores are flaking. The area around the instruments is very dirty, and the headlight is pointed up at the wrong angle, suggesting it's been sitting around for a while.

I'd like to see a shot of the rear of the motorcycle -- was the fender cut off? What about the tail light assembly?

Guess I’m missing something.

If the cylinders have not been replaced AND it has been ridden & used, there is no difference between this bike’s likely needs and those of a V7 Sport in the recent thread where the new guzzi guy’s butt has been getting the complimentary Crunch & Munch about what he oughhta do…  In case you missed it,   https://wildguzzi.com/forum/index.php?topic=115513.0 (https://wildguzzi.com/forum/index.php?topic=115513.0)

Budget accordingly now or you’ll budget accordingly later.

I also thought this same green T3 was offered on c/l earlier this year and discussed here about likely needing a full rehab because no cylinder details were provided or forthcoming.

You asked so I will give you my 2 cents. The exhaust system sez the bike might have been used for TT (tavern to tavern riding). The seat cover is baaad. You are buying a pig in a poke. You might be able to buy it and just ride OR it will become a money pit. I wouldn't pay over a grand for it.

Good luck in your choice,

949 big bore kits are available for $309. Either way I budget $1000 +/- for new cylinder kits or replating and new rings and hope it stops there.

I see now. I know from installing the same kits on a customer's Eldorado that the piston assemblies are 50 grams heavier than the original 83 mm piston assemblies. Unless the crank is rebalanced or the weight is brought down to match, the engine will vibrate considerably more than stock. I had custom-made lighter piston pins made, which added nearly another $100.

Yeah, I'd keep looking or your going to end up with a $5K+++ bike worth $3K.

From my experience:

Needs the starter relay rewired to prevent "click, no start".

Should have a relay wired into the coil power circuit so that the kill switch doesn't have to handle all the load, only switches the relay.

Needs a better transmission breather than the stock "mushroom", otherwise gear oil burps out all over the top of the transmission, when it's filled with the correct amount.

Rear drive should have the pinion oiling modification done, and ring gear lock plates removed.

Watch for "valve stretch" - clearances closing up. If they are, then chances are a valve is getting ready to break. Replace with new valves and Nevada springs.

Post by: Chuck in Indiana on June 30, 2022, 06:39:52 PM
^^^ What Charlie just said. If 5th gear whines, it is because the "fix" of oil burping out of the breather was to put less oil in it, causing starvation of 5th gear.  :rolleyes: It won't get better. There is also another mod to the rear drive to push oil into the pinion bearings. I did a tutorial on this stuff, but photoblockit stole the pictures. It's not hard, though.
That said, they are solid little bikes once sorted, with great weather protection. I wouldn't hesitate to take a sorted one across the country.

Bought it. Everything is there but it'll need some refurbishing. It's. running rich and won't take full throttle as if the choke is stuck on. Will start with full maintenance and probably carb rebuild. If valves won't adjust I'll replace them and the springs as Charlie suggests though at 15K, is that even a worry?

Post by: Antietam Classic Cycle on July 02, 2022, 04:01:14 PM
Just check the valves, adjust if needed and ride. For the first couple of thousand miles check them a little more often than you normally would to get an idea if any are closing up quickly.

Really a great idea with any adjustable valve bike, car, equipment, anything. More so if it needs a fair bit of adjustment when you check it.

Nice looking bike! Enjoy

Pulled the plugs to do a compression test - they were black and wet with gas. The compression was 155 on both cylinders. I'll check valve clearances first then look at cleaning the carbs. Ordered parts to relocate the breather. Will also look into doing the starter relay once I find the thread on how to do so...

Rewiring the small block starter relay.

The trick is in the brown wire.  It leads from the right handlebar to the relay socket under the side cover at connector 30/51.  From there, it is joined by a small brown jumper wire from connector 30/51 over to connector 86.  Disconnect the relay from the plastic relay socket.  Now look at the receiving side of the relay socket.  Each terminal has a slot with a small notch.  Reach into this notch with a small jewelers screwdriver.  Inside is a little tang on the female spade connector.  You need to flatten this tang so that you can pull the wire and spade connector out from the back of the relay socket.  We need to do this to swap the position of the two terminals within the relay socket.

Once you have both of the brown wire terminals removed from 30/51 and 86, then cut them apart as close as possible where they both join at the old 30/51 terminal.  Now, you have the wire from handlebar with a spade female on it and you have a short two inch wire with a spade female terminal.

Use your screwdriver to bend out and restore the little tang on the back of each female terminal so that it acts as a snap lock when you insert it back into the relay socket.  Now, reinsert the two terminals into the connector block BUT swap them so that the harness wire from the handlebar now goes directly into 86 and the short two inch wire goes into 30/51.

Now, manufacture a short red wire.  Perhaps 16ga and ten inches long with a ring terminal at the battery end, an in-line automotive fuse spliced into the middle and a straight crimp connector at the business end.  Splice this new jumper directly to the two inch brown wire dangling from the 30/51 position and install the ring terminal directly on your battery positive post.

You are all done.  Now, the 86 terminal only carries the load of the little relay electromagnet coil.  The 30/51 terminal (which gets energized when the relay closes) has a new, fat, short routing directly from the battery, throgh the relay contacts to the starter solenoid.  No more CLICK when you hit the starter button, just vrooooooom.

Agreed with Charlie... I wouldn't be too worried until you see the exhaust valves need loosening 3+ valve adjustments in a row...  I did mine when I was adjusting valves every 1,500 miles and seeing the exhaust valves were tight every time.

Adjusted the valves (exhaust were tight), adjusted the enricher cables (not closing completely), installed new spark plugs. The bike now runs well enough for a shakedown ride or 3.

Next up is the starter rewiring, putting a relay on the horns, and a more complete tune w/ fluid changes once the parts arrive. Also need to get the tach and turn signals working.

Would like to find a new rear fender as the original was cracked then poorly repaired. Also searching for a left side cover grill (black section that attaches to the cover itself). May need to go with standard V50/65 ones as SP parts are proving elusive...

The rear fender on my v65 also was broken, so replaced it with a steel one from a late 60's Triumph. The front came off a Honda. I think the Guzzi Nevada had steel fenders, I've seen a few on eBay.

The (metal) rear fender from a V50 or V50 II will work also, I did that on customer Steve's V65SP.

If a seller can't get the models correct that the part fits, then I'm very reluctant to buy from them. The V35 and V50 77-79 had Bosch electronic ignition and no camshaft "nose" like the later V50 III, so it won't work on them. The Autoparts Premium unit looks like a Dyna S knock-off.

I bought a Dyna S for my V50 III, but haven't installed it yet. In my experience, they are very reliable on customer's bikes. Sometimes it's better to spend the extra $$ for a known brand, rather than a knock-off...

Did some more wrenching on the V65 this weekend. Found out there was no air filter when I went to install a fresh OEM pleated element. Well, there WAS a K&N in there but completely dry so may as well have been nothing. Guess that's why they're called 'rock screens'.

With fresh gas and Sea Foam in the tank the bike is running pretty well. Not the low end torque of a big block but noticeably stronger than a V50.

Found the tach cable broken. Ordered a good cond. used one on FleaBay so hopefully all it needs is the cable replacement. I'll keep short shifting until I get the tach working.

Started going through electrical things and found I had 4 good bulbs with bad connections - cleaning and tightening the contacts got them working. Adding a relay for the horns and re-doing the starter relay are next.

While you are at it.. take *every* electrical connection apart, spray with Caig DeOxit.. accept no substitutes.. replace every suspect spade connector with a new one, remove the points plate and clean/lube the advance mechanism, etc. Your old small block will love you and give you good service.

Adjusted the valves (exhaust were tight), adjusted the enricher cables (not closing completely), installed new spark plugs. The bike now runs well enough for a shakedown ride or 3.



if the next time the exhaust valves are tight again, they are stretching , and will eventually break ( heads dropping off)
guzzi introduced a upgraded valve spring in 1990 ( actually 40% softer), to solve this issue.
instead of the original double spring it is a single progressive wound spring.
it can be retrofitted with a slight modification of the spring retainer.

i changed the exhaust valves on my V65NTX last weekend, the valves had stretched 1.6 mm
originally 93 mm, mine measured 94.6 mm
i think i caught them just in time.

Has anyone found a suitable spray can of Guzzi Red? The PO 'touched up' several panels with what looks like a generic red that isn't even close to matching...

Valve failure carnage photos...
Head of the valve popped off, was hammered smaller by the piston and stuffed back into the exhaust port.

Didn't do the piston any good either.

Normal valve on the left, bulging ready to fail on right.

I used valves from MG Cycle, with Nevada/Breva 750 springs, seats and retainers.

Might be best to take a body part with original paint to an auto body supply retailer and have them mix an aerosol can of paint to match.

Thanks Matt - appreciate you pulling the plastics out and taking pictures. From what I see my stuff is structurally in better shape though the paint isn't as good. Looks like it'll be less work to rehab what's already on the bike.

Just need to find that dopey grill for the LH side cover. There are V50 bits available on the market I can probably make work if nothing shows up.

Did you call MG Classics or Harpers for those grills?  Those guys usually have a stash of obscure old parts.

No. Sometimes the obvious escapes me. Hamlin's didn't have any but for some reason I stopped there.

Just bad timing on those grilles, my side panels were badly cracked. I believe I tossed them in the trash 2 weeks ago.

I used to have a V50III and sent the heads and manifolds to Ed Milich for valves, springs and flowing. Results were impressive no more valve float and strong pull through redline, I plan to do the same with these.
Cheers

eg:  You might try Ed Milich for those side cover grilles, when I got some v65 parts from him, he said he had a warehouse full of old stuff.

Matt: I'll email you about those parts.

My two sons and I took a breakfast ride around Hunterdon Cty to see how the V65 fared on a longer ride. 65 miles and 2:15 hours later it coughed once but otherwise ran fine. Other minor quirks are the "air balance tube" missing from the front forks so they're on the soft side with occasional bottoming and the transmission breather blowing a little oil (for which I was warned).

I put 20wt in my forks, but I haven't ridden it out yet. Seemed to work in my V 50

Update: the heavier oil and fork brace worked out great!  Bike was surefooted and agile.

Yes - that's what I was referencing when I said I'd been warned. I have the banjo and bolt on order.

Soft forks are likely due to sacked springs, not from from having zero pressure. Air pressure changes the firmness of the damping and not the springing of the forks. There's an air bladder in the top of the damper and when pressurized it restricts flow of oil in the damper.

^^^ and the bladder will probably be blown out.  :smiley: At least that has been the way of every old small block I've had. FAC dampers, Wurth springs and a Tarozzi fork brace will transform the handling.

Thanks for yet another tip Chuck. Will need to do some shopping for those bits. In the meantime, should I replace the valve and lines with an appropriate bolt to keep from sucking air into the forks?

MG Cycle has the forks and springs, I don't remember where I got the fork brace.

Thanks guys - the springs and cartridges are in my MG Cycle cart and I've bookmarked the fastfromthepast link. Those cartridges aren't cheap so I may just start with springs, seals, capping the forks, fresh oil and the brace.

I've successfully refilled the same type of stock dampers on a Le Mans III. Remove the black plastic piece the air fitting threads into from the alloy hex of the damper, remove the rubber bladder under it. Invert the damper over a drain pan and move the rod in and out to eject all of the old oil. Refill with 5w fork oil. Sorry, I didn't keep a record of how much. Basically one fills it until there is no "dead spot" in the damping and no oil is pushed out. Put the bladder back in, and cap back on.
