I bought a 07 predator 500. The top end was trashed. I am in the process of putting it back together. The plan is to do the big bore je560 kit, the head i just bought has stainless kibble white valves and springs and the motor came with no45 and no 46 hot cams. And i plan on putting a full exhaust kit on. has anyone had success with the hot cams and what would be the best jetting?

Hello and welcome to the site. The hot cams lose HP in the predator. the stock cams make way better HP in the upper rpms. With a pipe and intake I would start with a 170 main jet, the clip on the needle in the 3rd to 4th notch down from the top or blunt end of the needle and 3 turns out on the a/f screw.

Web cams make good power

Biggest power increase - bigger carb or mod yours
