Rincon 650· Registered
Personally have put the Jet Kit on the 500 Foreman and 650 Rincon. Great snap in the throttle. I put the jet kit in prior to the pipe and still saw a major difference. The 650 would wheelie with soe help, and with the jet kit, the 650 needed no help holding a wheelie for lond distance. it is worth $50. Comes with the proper spring, needle valve, and the main jet. Takes about 30 min and well worth it. Directions are easy as 123.
