This kit is to upgrade the MADASS 125 engine to a 142cc along with our new Race Head V2. The addition of this new head will dramatically increase the performance of your stock engine!! This kit includes our new Race Head V2 and while the new head may appear to be the same on the outside as our other KLX110 type race head, internally it has gone through numerous changes. The addition of roller rocker arms and a new camshaft are the biggest changes followed by bigger valves and ports. The exhaust valve is now stainless as well (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. Also, included is a piston with bigger reliefs to match the larger valves of the new race head. Mikuni VM26 carb and intake kit included with Stage 3 kit. Additionally, our head gasket kit 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! There are installation instructions posted on a video posted on our madass performance page. The parts are installed in the same manner as OEM parts.
