Race Ported Superior 26cc Big Bore Kit $115.00

These Superior 26cc big bore kits have been through our Race Porting procedure to enlarge intake and exhaust ports, widen transfer ports, increase compression, chamfer intake and exhaust ports to reduce the risk of the piston rings from snagging the cylinder wall plating. As well as an incredible port job we also lighten the piston and machine them to reduce the risk of seizing. We knew it would not be long before Superior stepped up to the competition with their awesome engine parts. This is a 34mm big bore cylinder kit for HE23HP and G230RC engines. Includes Superior cylinder, piston, ring, piston pin, circlips, base gasket, and spark plug. If the cylinder doesn't say 'SUPERIOR', then it's not! This cylinder has a thicker casting for improved heat transfer and the cylinder walls are finished ground for better than oem tolerances. Piston is cam ground and tapered for better fit at operating temperature. This kit will fit the G23LH,G230RC,G260RC,HE23,HE23HP,HE26HP, and all Sikk engines
