I've heavily modified this Honda NU50 into what you see here. It has a 70cc DR big bore kit, Weak Ends intake and exhaust, new CDI, Mikuni VM20 with 180 main jet and 22.5 pilot jet. I need to know a good starting point for tuning the card. Don't want to buy a bunch of jets, so could someone advise where to start?

Resored a couple of Suzuki FA50 this past year and will continue restorations as they become available. Next is a 50cc Harley Davidson (it's true!)
