Factory-Authorized Technical Documentation

This publication delivers comprehensive factory-level data for major mechanical overhauls. It outlines critical chassis systems, detailing frame alignment, fork adjustment for sidecar or solo configurations, and disc brake hydraulic maintenance. Engine chapters break down V-twin teardowns, cylinder head reconditioning, gearcase timing, and crankcase assembly procedures for both powerplants. Additionally, the final sections provide electrical system troubleshooting steps covering the alternator, charging components, and ignition timing sequences specific to 1980 and later models.

Engine and Chassis Specifications

Inside, mechanics will find technical specifications essential for professional engine work. The literature includes tolerance charts for valve guides, tappets, and piston fitment. For example, mainshaft drive gear end play is documented at 0.0005 to 0.001 inches, while spark plug torque is set between 18 and 22 ft-lbs. Intake valve clearance for the 1980-up engines stands at 0.0020–0.0040 inches. Technicians will also discover exact grease, oil, and sealant requirements for every assembly point, ensuring any repair adheres strictly to factory standards. Please remember that mechanical work involves inherent risks; always rely on certified procedures and proper workshop equipment to ensure personal safety and vehicle integrity during maintenance operations.
