Just received a kehin 28mm. I purchased some main jets with it also. I installed a 152 main to start with and left everything else stock.
My problem is the motor doesn't rev out. When I ride it there is no power like it's running too rich. Mods are pro circuit exhaust, premix 32:1, no airbox lid, ported cylinder, wiseco piston.
