Hi! I'm new here and have a question about top end noise in my '84 VF750F. It's not the cams, they've survived unscathed, and it's not the valves, I adjusted them about 3 hours' use ago. I remember reading somewhere about 2 or 3 years ago about the cam drive chain tensioners that apparently stick a little as the engine ages (there's 24,000 miles on the bike now), and how to unstick them. Does anybody here know about this? I'll search this forum for what I read, all 200-odd pages! Thanks in advance for any help.
