My scoot started to develop a very nasty vibration which I think comes from the transmission somewhere but I'm only guessing. The frequency of the vibration is constantly changing as I'm accelerating. It wasn't this bad when I bought it that's for sure but it is getting really annoying now. We had a look at all the transmission parts when we replaced the rollers/belt and everything seemed to be fine. Scoot: Y-reg VXR 180, 13k miles, serviced 2,5 miles ago (roller weights, oil, belt ect.) Any idea or advice would be very welcome! cheers Edit.: not sure if it is related to this problem but my fuel consumption is very poor, something like 50 mpg (should be 70-80 mpg)
Have you looked at the engine mount needle roller bearings ? Very common fault with 4t piaggio's . Also inspect the needle bearings inside the clutch , the clutch springs and the complete assy, also main bearings maybe?
