Hi all So had this issue for a while when I let off the throttle my bike sounds like an air craft landing lol. It appears the belt is rubbing on the casing. So bit of background I've changed belt and replaced all bearings in the transfer unit. Any other ideas what this could be? The bike is a gilera nexus 300ie
I've seen this a lot on all types of scooter, does your engine have the plastic "idler" wheel in the middle of the case?
