This kit is similar to our other complete 143 kit but includes our Race Head V2, camshaft, and a larger intake manifold. While the this head may appear to be the same on the outside as our other race head, internally it has gone through numerous changes. The addition of forged aluminum roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. The exhaust valve (like the intake valve) is now stainless steel too (21-4N material). This all adds up to a cylinder head that puts out a professional level of performance yet is still affordable for the privateer rider. The kit also includes an all aluminum ceramic coated cylinder. This cylinder is lighter than a steel sleeved aluminum cylinder, reduces friction (increasing power), improves sealing, and provides better heat transfer (runs and cools down quicker). Along with new roller head and ceramic cylinder bore kit we include the proven Mikuni VM26mm 606 series carb kit with a larger intake manifold. Unlike other kits, our head gasket kit also includes a head o-ring set and exhaust gasket so you don’t have to re-use your old ones or make a trip to your local dealer to get new ones and spend more money. These are high quality parts and require no machining to the cases or other modifications – bolt on and go! If you are racing the stock-mod classes this is one of the best engine set ups you can purchase to be competitive.

There are no installation instructions, but if you can replace your piston, you can install this kit as the parts are installed in the same manner as the OEM parts. However, its highly recommended that a professional install this kit and make sure its tuned and jetted properly. We have a wide selection of VM26 jet kits listed in our store.
