my brother has a blaster with an lrd exhaust k&n filter air box lid off, and my cousin has a stock blaster that is faster. i think that the jetting is off, what should the jetting be for sea level (we mostly ride at the oregon coast). also it barley runs where we live at 3200ft or so. it had a 310 main when we ran it against my cousins blaster.


p.s. i never really rode it so i dont know much more.
