6321 - 7.7hp Full Mod Zenoah G320RC 31.8cc Long Block

This long block can be order with a OEM Zenoah crankcase or our billet crankcase in the drop downs. G320RC vs G340RC the G320 revs higher due to the smaller stroke crank and the G340 being a stroked engine has more torque.

We're proud to announce the release of our full mod G320RC 31.8cc long block. 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.  

G320RC has the following improvements over the G290RC
Larger crankcase bearings
Larger lower connecting rod bearing
Larger needle bearing
Enclosed transfer ports with removal plate
New carb
