I just recently bought a 03 shee with t-5, k&n filter and outerwear, pro design filter adapter, boost bottle, v-force reeds. When the guy first bought the bike he had the bike jetted with the t-5, k&n, and boost bottle, and the 1" breather in the lid. The later removed the entire air box and now the bike is running too lean. I'm going through exhaust clamp left and right. I think it has 280 main jet and i dont know where the air/fuel screw is dialed that, and the needle also. I run race gas (c-12) w/ 40:1 ratio (maxima mixing oil). i was just looking for a starting point so I can run the bike on the dyno to tune. I usually ride the dunes and desert riding year-around.
Thanks for the help
