Common Concerns:
Potential for stator/rectifier failures (common on many V-twins of the era), fuel pump issues, occasional electrical gremlins. Clutch slave cylinder leaks can occur.
Maintenance Tips:
Regularly check voltage regulator output, keep battery terminals clean, maintain the cooling system diligently, and inspect the clutch slave cylinder seal.
