Further to my probs with cosa clutch dragging I decided to give the old type p2 clutch a try which had new corks, steels n mallosi springs fitted, however I'm finding that when releasing the clutch lever when stood still it makes a noise (i cant describe what its like) and surges forward, has anybody got any ideas as to what may be happening and how to rectify it?

Well, I think from the several mates in my scooter group who have Vespa (inc. mine) they sort of 'rustle' then it changes when the clutch is pulled in. Mainly due to the clutch plates moving back and forth a bit in the basket. The oil dampens the sound. If you want to hear how they work as dry clutches see from 45 secs in As to the jumping forward, are we talking clutch drag or a throttle that isn't shutting? If drag I am still sticking (or actually, not sticking lol) with the ATF suggestion as I have done about 230 miles on the stuff so far and it's great. |

The clutch on my px only makes this noise when pulling away from a standstill as I say I can't describe it at a push it sounds like the rear wheel is spinning although it isn't as I've had friends observe me as I set off no its not drag as the scoot doesn't feel like its creeping forward when the clutch is pulled in, instead its like sudden surge of power to the rear wheel although the levers only being released gradually

I don't think it is as it didn't occur with the cosa (that drags) I'll try replacing the bronze bush n shim n see what happens from there

Older clutches are more noisy than Cosa ones.
You did soak the plates in oil?

Nik, yes the corks where soaked in oil. Bsr65 I also replaced the steels which aren't warped. After further research i learned that the bronze bush needs to be held firmly in place, something I didn't realise when i replaced the plates and recall being able to slip the one that's in off and on easily, although its outer surface isn't worn is it worth trying to loctite it in position?

It's pretty much an interference fit, meaning that it needs to be pushed home firmly.
Under no circumstances locktite it though, a bush is the most simple form of bearing, and so needs to be able to move.
