I was riding last night and i looked down and saw that the whole head pipe was glowing cherry red. It was dark out so i could see it. I know it is running really lean since it's running that hott, but the fan did not kick on so i don't think it is running that hott. Right now all i have is a DMC full exhuase, k&n filter with outerwear, air box lid on with no holes cut in it. i have the needle in the middle clip, and a 138 main jet. I leave saturday i believe for a week trip to silver lake. anyone have any suggestions on where to go from there. I have the dyno jet kit, i know this make a difference from the sizes of other kits. I need to know if i move the needle if that will screw everything else up. thanks for the info.

 

Jetting is part art and part science. It requires experience, which you don't have time to obtain. You are in a hurry, so pay to have it done by a professional.

 

running massively lean, i'd just go with a larger main, go to a 165 or one 155 and see what that does and if its rich just go down another size

 

I changed to a 148 main, got rid of the dyno jet main jet, but keep the dyno jet kit needle, is that okay?

 

as long as it doesntr spit or spudder that'll be fine
