so I'm still new to mopeds in general and i read a lot of forums but could someone tell me what to exactly look for when I'm trying to tune my carb.... i have an a55 with bi turbo and dell 15.15. a lot of people say to try jetting anywhere from 60 to 80 but how will i know if the jetting is right? so for example how do i distinguish that a 72 jet is better then a 68 act. is their a specific sound? doses it feel different? my biggest worry is that i seize the piston up from it being to hot... never jetted before only have theory of jetting.
