ca320 - .005" (0.15mm) Copper Cylinder Gasket for RC Engines

High-compression, reuseable thin copper cylinder gasket. Copper gasket is .005″ (.015mm) 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: CY27RC motors require 2 stacked gaskets for proper clearance. CY29RC engines and engines with stroker cranks installed will likely need even more. 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.
