i have a 2007 yfz450. the bike has hotcams intake and exhaust, k&n filter, leo vince full exhaust, negative 6oz flywheel, and a quick shot2. i bot the bike brand new with a filter and white brothers pipe on it. now with all the other mods it runs like crap. what jets-pilot and main do you suggest i run. it bogs like no other and snaps and pops when you hit the gas. i have an after market fuel screw as well. im at my wits end with this bike! please help!
