Kibblewhite at 2011 Dealer Expo
Mike Perry from Kibblewhite Precision Machining has quite a few different kits for all models of UTV’s. They have standard and oversized vales as well as high lift spring kits that increase pressure so you can run more aggressive cam profiles. These adjustments are made to get higher RPM at the top end.
