Hello
Thank you for your response
It happens with all clutches which you tried ? Original, Polini, Pulley?
1) Only with Dr Pulley Hit clutch i have this sound, i have remove it from my bike and i installed the OEM (original) clutch and the everything is back to normal (no sound).
Did you ask a mechanic from Piaggio? ........Can you see any scratches or other signs of a contact in the bell?
2) It was the first time that the mechanic installed a Dr Pulley Hit Clutch, he examine the clutch and the drum and he didn`t see any bad marks or scratches on them.
And it happens, when the clutch linnings are getting contact with the bell?.... And it stopps after full contact and during driving?
3) Yes and yes....
Is it possible that the Hit Clutch needs time untill the friction surface of clutch weight is fully matched with the bell ???
Have you seen something like that again...???
