Want to make huge power out of your engine?! Start with the V2 cylinder head’s larger stainless steel (21-4N) valves, better porting, roller cam, and forged aluminum roller rocker arms that allow the engine to rev quicker, farther, and make much more power than the stock setup. Add the high compression 54mm bore kit that brings up the bore to 114cc and makes for a strong power band. Finish it off with Mikuni’s VM26 carb in our carb kit adding up to a professional level of performance at an affordable price for the privateer rider. These are high quality parts and require no machining to the cases or other modifications – bolt on and go! There are no installation instructions, but if you can replace your piston, you can install this kit. If you don’t have any experience working on your engine, we highly recommend having a professional technician install this kit
