I am running a pro flow with K&N and the TC. I am running at 170 main NCVQ needle at 4th clip and 45 pilot. That seems to be the best one for me.

I think I must have an air leak because, I actually have a yz engine in my R frame bored to 440 but I'm running open airbox uni 52 pilot stock needle on fcr 39mm and a 195main and my head pipe is glowing red hot? anyone else have any suggestions.
