After my original exhaust rusted to pieces i bought a brand new sito plus exhaust. After that my scooter has a bit more power on low revs, but less power on hig revs. To get the best performance of my scooter i've understood that I need to rejet my carb. What size should my main jet be?
Carb. SHB 16.15
Main jet 65
Idle Jet 42
Is there anything else I should do to make my scooter work properly?
