Hi friends. I own a Kawasaki Vulcan 1500 Classic from 1997, I recently had a noise (banging) on the right side, in the clutch area (more precisely right in the center of the engine) - the noise is present only in the cold engine, it disappears after the engine heats up. I am currently using Motul 10w50 synthetic oil. Does anyone have any idea what could be causing this noise? Thank you guys!
