High-compression, reuseable thin copper cylinder gasket. Fits Zenoah G240RC / G270RC / G231PUH / G260PUH / G260PU / G231PUM / G260PUM engines (i.e. 4-bolt cylinder style engines). Also fits TS 4-bolt billet crankcases. Copper gasket is .012″ (0.30mm) thick – stock gasket is .020″ (0.50mm) thick. Installing this gasket reduces the squish clearance in your engine – usually the easiest way to increase power and reliability of a small 2-stroke engine. You should experience a noticable improvement in low end torque and throttle response as well as slightly increased top end RPMs. DDM recommends using 95 octane or higher fuel after installing this gasket.
Note: Be sure to check your squish clearances when using this gasket. Failure to maintain proper squish clearance can result in a severely damaged or destroyed engine.
