I did a valve leak test on the worn cylinder when I lifted the head. It had a slight leak in the intake valve. I seated the valve grinding it with fine grinding paste, which did the trick, so I now know that the leaking here is from the rings. As this cylinder/piston seems worn considerably more...
Hi John
Did a leak down test. Left cylinder 20%. Right cylinder 10%. Lifted both cylinders yesterday. Right cylinder looks like it's been doing very few km, perhaps true to the 15.000 the clock shows. The left cylinder has done more, There are wear edges from the rings in the top and bottom of...
Thanks John!
Oil is spot on, and your other suggestion, is what i fear although the bike only has 16.000 km on the clock and purrs like a kitten. (hopefully not 116.000) although there are indications to that fact…(a very dirty sump now cleaned out).
Never seen this before on my other SB's (7) - it seems like the engine constantly is pushing oil into the breather box, which on this model is a combination of the oil breather separation box and the air box. After each ride, oil is dripping out the air box drain.
Any ideas? I have a V50/III...
I know of a nice setup, that only requires a simple airfilter at the end of the tube comming from the oil collector/breather box connected to the valve covers.
Not complicated at all. The filter is only to prevent, that there are no dust sucked into the oil collector/breather box. That makes it...
I've had this happen with my V35C, V50/III and V65 Lario, at least dropping one cylinder - common to the bunch is that they have point ignition which includes condencers.
When getting old they fail when getting hot 100-130c. That will cause rough running or make one of both cylinders cut. The...
The part numbers of the two frames are different,so I'd be carefull on that approach.
Sorry for your trouble, I have a Targa - and it's a wonderfull bike.
Cheers
Just saw this thread - very cool! Congrats - it's evident you did not know what you have gotten yourself into buying a V75/4 - :shock: :o :? :dry: :? 8-) I assume you do now.
The most powerfull SB Guzzi ever made - and the record still stands :)
The 8V SB's are known to have valve...

Ciao
I joined a few months ago, but decided only now to become active. I like there are dedicated topic folders here, as I only own SB's - although I like all types of Guzzi's.
Saluti 8-)
Hi Geno
This is a real nice bike and one with most qirks and niggles taken care of compared to the mark 1 and 2.
Oil is a dangerous topic :shock: :whistle: :dry: :unsure:
There are many good oils on the market. One thing you should take into consideration is, that Guzzi's has flat tappets...
