ESP "High-Rev" Modified Zenoah G320RC / G320PUM 38mm Piston

ESP "High-Rev" Modified Zenoah G320RC / G320PUM 38mm Piston from Earth Surfer Products.

New for 2018 is the ESP 38mm High Rev Piston (G320/G340 engines).

The piston gives your exhaust port 5.5 more degrees duration, which helps high rpm power, with very little compression loss.

Fits stock and ported engines both RC air cooled engines and G320PUM marine water cooled engines.

Thanks for using my stuff. I appreciate it much. -Doug @ ESP
