I recently purchased a bike with 38mm Mikuni's bored out to 41mm. It run but not very well. Slight bog off the line and breaks up a little on the top end. Seem very rich blowing raw methanol out the pipes. Can anyone please give me some advice on the jetting/needle for these carbs for the following conditions:
Sea level, 200 psi compression, plus 8 timing, 7mil, drag ported cub. I think it currently has 55 pilot and mains drilled out to .116, not sure on the needle
I have trouble clearing it out at the line so the needle may be too rich. Also, I was running it with the power jets screwed in 1.5 turns from wide open.
Thanks for the advice!!
