USED PARTS DISCLAIMER: 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, or other cosmetic wear. Any known damage or defects are noted when known. Unless otherwise stated, the photos show the actual item being sold and are considered part of the description.

BORE / IDENTIFICATION: Measured 3.19 in. Factory 1000cc Ironhead bore is approximately 3.188 in, so this appears to be essentially standard bore.

FITMENT NOTES: The bore measurement strongly indicates a 1000cc Ironhead cylinder because the factory 1000 bore is about 3.188 inches. The 2028 marking may be a casting/date/foundry code rather than a service part number. Confirm front/rear position and all physical dimensions.

FITMENT: Buyer is responsible for verifying fitment before purchasing. Fitment information is provided as a reference based on available part numbers, casting marks, measured dimensions, donor information, and published references. Motorcycles may have been modified over time. Compare the part number, casting, mounting points, bore, dimensions, electrical connections, and photos with the part currently on your motorcycle.
