After getting my Raptor back from the shop, were a 11:1 piston, Hotcam Stage 1 cam, and port and polish job was done my quad is really hesitating in the low rpm's. When riding the trails it really bogs down if I don't stay on the throttle. I jetted the bike when my exhaust was put on and it ran very good in all rpm's but now its not so good. Could this be a jetting problem. Or the fact that I am now using racing gas, or what just want it fixed.
