Im installing a hotcams stage 1 cam, LRD pro 4 series full exhaust, and a K&N filter with airbox lid removed. I was wondering where i should start with the jetting. From what i have read, the jetting on the 450r is crazy. I bought a jet kit but the main jet size only goes up to 180. Ive read and talked to people who put after market exhausts on and say they use 185 and even 190's. What do ya guys think?
