HARLEY York Electric Starter Kit Fits 1954-1957 FL, rigid frames

York electric start kit is designed exclusively for rigid frame 4 speed models with a splined motor shaft in a generator type motor Knucklehead Flathead Panhead or Shovelhead model. Requires a shorter oil tank and includes the oil tank base plate to allow clearance for the starter motor. Installer can also modify original type wrap around oil tank by removing the rear bracket and re-welding in a raised position. The rear fender and tin inner primary must also be modified for installation. The battery required is the Anti Gravity 12 Volt 16 Cell battery. A 84 link primary chain is included as the chain tensioner assembly requires the longer chain. The primary chain tensioner is mounted to the 2 rear motor mount bolts for a secure mount. The starter motor is mounted to a cast steel housing mounted to the transmission mount plate so it effectively drives the starter ring gear on the rear of the clutch hub. This arrangement requires the motor sprocket to be offset 1/2 inch for this requirement. Kit also includes a splined motor sprocket and spacer. We recommend getting our oil tank and inner primary for your your application. Starter spring retainer washers available separately. FITS HARLEY: 1954-1957 FL, rigid frames
