Serious newb question.
The only performance mod Iíve made to my Stella 2T is a Polini box exhaust, plus a Piaggio predrilled airfilter, plus up-jetting. Iíve been very pleased with the increased power, especially the increased midrange power. First gear has become borderline useless, but otherwise the scooter accelerates strong and smooth to somewhere over 50 mph (Stella speedo provides only vague suggestions) where it will run happily all day long. That is 10 mph more than the speed limit on any road I am likely to be using.
The only question has been a consistent and prominent pop, pop, pop, pop, pop sound whenever the scooter is moving and the throttle is closed or nearly closed. Iíve messed around with jetting and timing and nothing has changed.
Is it safe to assume the pop, pop, pop, pop, pop sound is just the nature of the beast, and that no pistons are being harmed in the making of this movie?
