Additional Information
NOTE: Uses Vertex #23910. Use with Hot Rods Crankshaft #4259 for 462cc. This kit will come with Vertex Gaskets. Due to manufacturing variations of OEM cases, slight modification of the crankcase may be required to allow proper fitment of the big bore cylinders. Sufficient clearance must be obtained to allow the cylinder to seat on the base gasket surface without any interference between the cylinder and crankcase.
