Hello everybody
My 03 Vespa GT 200 L 31.000kms have a curious behavoiur :

when I release the throttle its sputtering very often, and when I turn off the engine, a cople of seconds later its make a little "puff" fromn the exhaust.

rich or poor carburation?

needs a adjust valve clearance?

Anybody maybe have the same "problem", or know which can be the cause ?

thanks a lot
