Hey, i have a vespa Ciao. Stock motor plus delorto 13/13 and a polini top mod. Right now i up jetted to a 75 jet. BUT its running hella fat. four stroking and such... So what'd you use? i'm at altitude in denver. so i can adjust based off recommendations
Thanks

if it's all stock other than that carb and pipe then the 66 the carb came with will be rich. go back to that, then go down a few jet sizes at a time untill it stops four-stroking all over the place.
66 maybe even a 64
Thanks guys, I'll drop it back to the 66 and see how it works.
Id go 64, maybe lighter, especially for denver. Get a Malossi filter, too...you really only see benefits when you open up both ends of the intake/exhaust circuit.
OH! I forgot that detail. It does have a malossi filter setup. Once i can get to the shop and do a jet swap i'll be set.
We're similar altitudes. I'd say between 56 and 60.
62 is what my friend is running on his kitted SI in South FL, like six inches above sea level...
I've got a 65 i just put in right now. Stopped four stroking. I haven't been able to get a plug chop in cuz my spark plug puller is too big. That'll come soon.
Thanks everyone
