Help diagnose engine noise!
My 1977 CB750F has a troubling rattle that I can't quite figure out.
I've checked the valve tappet clearances and adjusted the cam chain tension regularly, and recently, without any significant difference.
I'm either doing something wrong, or there's something else it could be.
Any ideas?
