A nominal 3-5\/8 bore is 3.625 inches, so final bore size, taper, out-of-round, and piston clearance should be checked with precision machine-shop equipment. The 80806B and 80811A markings could not be reliably tied to a specific manufacturer catalog during research.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUSED PARTS DISCLAIMER:\u003c\/strong\u003e This is a used motorcycle part and may show normal signs of age, installation, removal, storage, and previous use, including scratches, scuffs, discoloration, surface corrosion, paint loss, oxidation, or other cosmetic wear.
