hey guys my buddy has an 03 raptor 660 that ran good but was a little choppy in 4th gear and up...so we did a carb rebuild kit on it set float heights correctly but the bike still won’t rev, its doing the exact same thing the TORS system does on the blasters bogs, backfires, and stalls on full throttle he has done the reverse bypass and the parking brake isn’t stuck...any ideas on why it won’t rev up?
