So what have you done to the motor to have the need for that pipe?

So after riding the bike all week after getting everything adjusted it rode pretty good. I only found one problem. If the throttle is pinned all the way then it starts cutting out and not gaining speed. If I back off just a c*nt hair then it stops cutting out and starts gaining speed again. Is this a main jet being too rich issue or possibly throttle adjustment issue? This happens at 70+ mph.

I've run those jets on a stock motor then I added a cam and various different pipes then 9.5-1 pistons.
