Alright, I've got the stock 122 main jet in there. The mods I have to the engine are full system pipe, k&n filter, and no lid. It will ride fine just when I get on it it sputters for a second. Should I go with a 125 or a 128 main?

i run a 128 dyno which is like a 135-140 stock type. I run a lid too so you probaly will wont something around a 130.

Well I just put the 130 in there, and it feels a lot better, but it still bogs just a little bit. Maybe its just me, but it just does it in the higher gears.

are you sure that you are reving it out enough to shift into those higher gears?
