Smart Phone Integration:
Not applicable for this era of motorcycle.
Oil Change:
Every 2,500-5,000 miles or annually, whichever comes first (check manual for specific interval). Engine oil, transmission, and primary chain case often share oil or have separate recommendations.

Engine Vibration:
While rubber mounting mitigates vibration, some is inherent to V-twins. Issues could arise from worn engine mounts.
Carburetor Tuning:
Keihin CV carburetors can require periodic adjustment for optimal performance, especially after altitude changes or modifications.
Belt Drive Wear:
Belt tension and alignment are critical. Wear or damage to the belt can occur if not maintained properly.
Electrical Connectors:
