Refurbing my v65 SP (was '77 T3)
« 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?

If "top end" work means the original chrome lined jugs have been replaced or relined, then maybe $3,000 or $2,500 would be better. If the chrome bores are still intact than $1000 would be as high as I'd go.

Still no reply from the seller. If the cylinders are original are replacements available?

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

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,
Tex

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.

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.

^^^ 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.

I contacted this guy when it was posted previously. I asked him about the valves and he was unsure if the valves and springs were original or changed.

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?

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.

Does anyone have a copy of a parts list for the V65 SP or can point me to one? Dealer says that Guzzi has dropped that model from their online system and the couple links I have don't include this model. Thanks.

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.
