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 3.49 in. This could represent a roughly +.050 74ci cylinder or a near-standard 80ci bore (nominally about 3.498 in). Casting and physical dimensions are needed to distinguish the application.
FITMENT NOTES: Do not list this as a definite 74ci or 80ci cylinder until the base spigot, cylinder height, casting details, front/rear orientation, and exact bore are checked. The measured bore sits in the overlap between an overbored 74ci cylinder and a near-stock 80ci cylinder.
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.
