Used with 3-5/8 big bore cylinders in combination with 4-1/4" (88"); 4-1/2" (93") or 4-3/4" (98") stroke with 5.375" (88"); 5.500" (93") or 5.750" (98") long cylinders and stock heads. Kits include forged pistons; wrist pins; wrist pin clips and piston rings. Note: 98" engines must use small 8-1/4" o flywheels. Note: In any and all applications the technician must be able to judge components for their suitability in combination with the other engine components; prior to installation. It is of importance that a knowledgeable mechanic will install & make adjustments as required. The rider must follow standard break-in and riding procedures for overhauled engines.
