We're proud to announce the release of our prostock G320RC 31.8cc engine. This engine is built similar to our previous prostock engines. To keep the price down we concentrate our porting/machining time to the areas that yield the most HP. This engine can be sent back to us at any time to be converted to a full modl We're very happy with the changes that Zenoah has made and it's turning out to be a great engine. Intake and exhaust ports are modified to our specs as well as the duration's. Cylinder is decked for higher compression and more power. Engine is complete with carb and clutch. Just bolt on your exhaust and filter and it's ready to run.
