hi mate

have you got any more details on the scooters set up e.g

variator
clutch
rear pulley spring
reed block
manifold
air filter

these part a the things you need to get the engine working right... and the engine will work better running a 19mm or 21mm dellorto carb

please get back to me on this side of the set up

BYS

maybe you should try 21mm carburateur, 17.5 isn't small a bit, or is it okay? : O ?
