Engine: 175, a Li 150 cylinder bored out to 175, no modification to ports.
Exhaust: BGM Clubman
Carb: Dellorto(scootopia) SH2/22
Main jet: 142
Pilot: 50
GP200 slide & atomizer
Smooth rubber elbow and good quality foam filter. (Binned the airbox)

At around-town driving, 1/2-3/4 throttle my if was white with a 123 main, and stayed like that as kept increasing. Not until 140 I started to get colour and at 142 it's perfect. It seams like a huge main jet, but on this primitive carb It's the ratio of atomizer to main that is important.
