Electrical Considerations:
Older wiring harnesses can become brittle; regulator/rectifier units can be prone to failure.
Carburetor Tuning:
CV carburetor requires periodic adjustment and cleaning for optimal performance, especially with aftermarket exhausts or air cleaners.
Belt Drive Tension:
Proper belt tension is crucial to prevent premature wear on the belt and bearings.
Brand Legacy:
Harley-Davidson, established in 1903, is one of the oldest motorcycle manufacturers, renowned for its V-twin engines and classic styling.
