ESP Zenoah 36mm 2-Window REED Piston (for use with Reed top ends only) - High Rev Version

NEW ESP reed case replacement 36mm piston, high rev version ESP High Rev piston for 2-port 36mm reed case ported cylinders: If you are not using a ESP reed case ported top end kit on your RC case reed engine, there is a very good chance your exhaust port is not opened much or not at all. In addition to the port windows, oil holes and grooves, (for much less piston wear), and light weight machining, these pistons also open up your exhaust port by 5.5 degrees in duration to greatly enhance the mid-range and top-end power, with power gains up to .75 more HP. If your cylinder plating is still in good shape, just install this piston with a new ring, and enjoy the extra power you deserve. Thanks for using my stuff. I appreciate it very much. Doug @ ESP Note: Piston Ring sold separately (see item ca333)
