We're proud to announce the release of our full mod G320RC 31.8cc engine. We're very happy with the changes that Zenoah has made and it's turning out to be a great engine. Engine is fully modified just like our normal full mods. Being the transfer ports are enclosed we can't modify them quite the same but they are modified. Intake and exhaust ports are modified to our specs as well as the durations. Just like a 30.5cc we cut the combustion chamber and reshape for more power. Engine is complete with the option to add/remove carb and clutch. Just bolt on your exhaust and filter and it's ready to run.
