Race Ported 27cc Big Bore Kit $89.99

These Sikk Toys 27cc 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. These SK 27cc kits also come with a lightened wrist pin. This is a 35mm big bore cylinder kit for the G230/G260RC/HE23HP/HE26HP engines. Includes cylinder, piston, ring, piston pin, circlips, pin washers, upper bearing,spark plug and base gasket. Can also be used as an upgrade for the G23 and HE23ZR engines. If you want the biggest displacement available then this is the kit for you. This displacement is so large it is not even legal for racing yet.
