Thanks for the input. The exhaust is a Leo Vince Handmade 70. Everything else is stock. The scooter is a Benelli Andretti M50(QJ). What jets should be changed and to what size? It also run like shit at 1/4 throttle. Would 4 gram rollers be better. Not worried about top speed. Just want this bugger to run smoother. Thanks Gents!
BTW Teddy, the scooter came stock with a touring pipe(looks big enough to me to be an expansion pipe).
I should probably also take a look at the plug.
