Smoke is not your indicator, the plug is. Ot is internal(aka combustion camber) so if it is white, toss in a size larger jet. I talked/ordered a airbox mod from hardrock and they tell you to jump from 1 150 to a 170. So that would give you an idea how restrictive the air-box is.

short version, it is lean. jump up in jets until it is carmel colored.

toss all the vents in and put a 165 to 170 jet in.

You are adding a lot more air, so go rich the lean it out, lean can burn stuff up.

aka no riding cause of a nuclear piston.

Also, you can feel the increase in power when you jet it right.
