Hey guys I have a Polaris 525 IRS with the KTM motor. I have a full CT racing exhaust open air box and jetting. I am putting 44rwhp now but I want to be in the 50s. I spoke to a guy and he told me to put a 806 cam and a JE 13.5.1 piston in it. He said that would get me in the mid to low 50s. What are yalls thoughts? Should I do something different? Looks like a good bang for the buck if it works. I really love to drag race on dirt and my buddies Honda 450 dirt bike smokes me on the top side.
