probably this. they are supposed to be changed quite frequently , every 3000 miles or so, but at 20-30 quid a set for piaggio ones , rarely get done. or you need to loose a bit of timber. ;)

How fast should a standard T5 go when read on a GPS? On the Vespa speedo it could be anything from 50 to 80mph :lol:

I have same prob with 172 malossi SIP JL pipe and uprated clutch. Wise to try small changes before spending too much dosh.
