[gretchy]

Hello any ideas which size jet is best for px125 with malossi 166 kit and sterling sports exhaust?

Ive put new spark plug in and checked it and it is light brown. Any help would be appreciated. Thanks

Gretchy,how olds the engine?
what carb/size do you have fitted?
What carb slide is fitted?
What crank are you using?
Are you using an oil pump?
what's all the jets you have fitted at the moment?

Or if you need a quick answer Google vespa px Malossi 166, sterling exhaust, jetting? And see what comes up. 😉
