✓Check the tubular steel chassis for cracking, particularly around the engine mounts and front suspension pick-up points on early cars.
✓Listen to the "bevel box" (which transfers power to the rear belt) for excessive whining; it is a known weak and noisy component.
✓Inspect the rear drive belt for tension and wear, ensuring it hasn't picked up stones or debris.
✓Verify the S&S V-twin engine has been serviced; check the exhaust mounts, which frequently snap due to intense vibration.
✓Examine the wire wheels for loose spokes, which must be "pinged" and tightened regularly.
✓Test the steering for excessive play, and be prepared for a very heavy clutch pedal.
