Assessing the Condition of a Harley Knucklehead

Before committing to a purchase, thoroughly assess the Knucklehead's condition. This requires a detailed inspection, ideally with the help of a knowledgeable mechanic or Knucklehead expert. Our team has restored several Knuckleheads, and we've learned that a comprehensive inspection can save you from costly surprises.

Engine Inspection

• Compression Test: Perform a compression test to assess the health of the cylinders. Low compression can indicate worn rings or valve issues.
• Oil Leaks: Check for oil leaks around the cylinder heads, base gaskets, and oil lines. Leaks can indicate worn seals or gasket failures.

Frame and Body Inspection

Electrical System Inspection

• Wiring Harness: Check the wiring harness for frayed or damaged wires. Old wiring can cause electrical problems.
• Lights and Indicators: Ensure that all lights, indicators, and switches are functioning properly.
• Battery: Inspect the battery and charging system to ensure they are in good working order.

Verifying Authenticity

Authenticity is paramount when buying a vintage Knucklehead. Counterfeit or heavily modified bikes are common, so verifying the bike's originality is essential. According to the Harley-Davidson Archives, matching frame and engine numbers are critical for authentication. — Middle Village, NY Weather Forecast & Current Conditions

Key Original Components

• Engine: The engine should be the correct type and year for the model. Look for original castings and markings.
• Frame: The frame should be the correct type and year, with no signs of modification or welding.
• Transmission: The transmission should be the correct type and year, with original gears and components.
