ESP G43L / G430RC HIGH REV PISTON!


New for 2020: The “ESP High Rev Piston” for the Zenoah G43L (G430RC). Works great along with both stock or ported cylinders. This is a modified version of the stock piston (DDM part number ca503, Zenoah part 4500-41110)

Finally, an easy way to get more performance out of your G43L/G430RC GSR40 engine. That engine has a small exhaust port and the casting is pretty thin. Because of the thin casting, porting will add more power and top rpm, but the exhaust port still can’t be cut big enough to get top performance out of the cylinder. This piston is a great addition to your G430RC/G43L engine, adding performance to stock engines that mimic a ported engine, and even more performance for the ported engines out there. The ESP High Rev piston will increase the exhaust port duration, while allowing the roof of the exhaust port to still be thick enough to remain strong. You can enjoy more mid-range and top-end power with more top speed by simply installing this piston, (recommend new rings too), in your G430RC/G43L engine. (Highly recommended to re-jet your carburetor after making any engine modifications)
