Hello all.
Just wanted to pass some info on since there has been a mad amount of jetting problems.
Mikuni jets are numbered based on fuel flow rate. Dyno Jets are based on orifice size. If your pipe came with jetting numbers you need to know what method or brand of jets they use/recomend. There is a big differance. I don't have my chart handy but a Mikuni 130 main is around a Dyno 146 main.
