Sbn 44 jetting

[nwcitizen]

Putting together a 750 big pin, staying stock other than I’m putting a mikuni sbn 44 on it. (It’s what I have) where should I start at for jetting and pop off spring? Thank you for any advice.

2.0 n/s 20-25psi popoff, start with 120 pilot, 150 main and go from there.

Make it fourcycle at full throttle and go from there. You cant tune without finding a safe starting point first.
