Hi,

Im using a 17.5mm carb with my Zip FastRider and a 93 jet. I have a TNT Helix filter which makes quite nice sound. The question is this how big should the jet be, because I didn´t test any other jets. Just put the 93 in and done. Any suggestions?

The setup:

Polini 70ccm Sport
Polini Small End Bearing 12x17x15
Malossi Multivar 2000
LeoVince ZX
Dellorto 17.5mm with a 93 jet
LeoVince 30% stronger clutch springs
Doppler Endurance Crankshaft
Hq Racing cranckshaft bearings with oil seals
Polini Carbon Reed valves
Malossi Manifold -21mm
Dayco belt
Denso Iridium sparkplug IW27
4.1g Malossi rollers
TNT Helix filter
Polini 15% stronger contrast spring
