jetting problem

[kellettkustumz]

i just put a set of 270 jets in my shee. im not sure what clip the needle is on. its got fmf fatty gold series pipes with power core 2 silencers. it also has a regular k&n filter with the snorkle removed with bulls eyes in the lid. no engine work. the reeds are stock. the air/fuel screw is 2 turns out, and the timing is advanced 4 degrees. it has some serious balls out of the hole but once you hit mid it flattens out and stays that way. it almost sounds like its breaking up. im at sea level and its about 45 to 50 degrees here. what do you guys think?

put in new plugs and try again.

pull the plugs after riding it and tell us what they look like

 

what did you change that made you want to rejet, and what was in it before that ?
