G230RC cylinder OBR race ported for increased top speed and improved acceleration. Adds 2-3 MPH and faster acceleration. Fits G230RC / CY23RC engines. This is the complete top end kit including OBR race ported 32mm cylinder, piston, ring, gasket, c-clips (snap rings), and pin washers - as shown in photo.
CNC ported and hand finished
All ports resurfaced and sanded
Exhaust duration/timing increased and port widened
Compression set for 91-95 octane fuel. Running race fuel can cause detonation and damage to the top end.
Cylinder decked to raise compression and tighten squish clearance. The stock cylinder gasket needs to be used. Running a thinner gasket or no gasket at all will raise compression too high and/or cause the piston to hit the combustion chamber.
