I have a question about theThe Jack Stackô
I have a PX125 Lusso. While waiting for my Polini 177 to be rebored and honed I have put my 20/20 carb and original cylinder back on. It also has a SIP Road exhaust fitted.
What would be a good starting point for The Jack Stackô on this scooter? 120/BE3 and a 102 main?
The only air correctors I have at the moment is 160 and 140. Should I get a 120?
I guess the SIP road needs a couple of numbers up from the original 96.
Undrilled original 20/20 airfilter.
