Ok now that its running I have another question, My airbox has large holes cut in it, a K&N filter and the muffler says Gemini Corona California on it. But when I took the carbs apart to clean them the main jets had the 95 and 102.5 stamped on them. This cant be correct for the mods? does anyone know of the correct jetting for this setup?

Those are stock sizes.
If airflow capacity has been increased, your jetting also needs to be increased.
How much? I can't help you there, will have to leave that to someone else.

the jet kit instructions say to use 102.5 jet on #1-4 and 105 jet on #2-3 and move the needle jet down 1 clip towards the point (or use 2 shims (included in kit)). And fuel mixture screw turned out from seated 3-1/2 turns. theres a few other mods to for racing bikes, but probably not needed to explain those.
edited: that's for a 4-1 header, K&N filter mod, so go from there I guess.Comment
