I've got a general chain question, regarding my other bike.
I've been running an o-ring chain for about 15,000 miles on my 1975 Honda CB750 K5. I replaced the sprockets at the same time. It seems as though it has hardly stretched at all; however, there are some major tight spots. When I check the slack in the bottom run of chain between the sprockets, it is very loose at one point on the chain. Then, I rotate the rear wheel about half way around, and it is much tighter. Right now, I've got it adjusted so that it has a 3/4" of slack at the tightest part, and the loosest part doesn't rub on anything. Is this normal wear? Is it time to replace the chain? What causes this? The adjusters are lined up with the second line from the front of the swing arm, so I've got a lot more strech that I can take up, but that doesn't seem to be the problem. I hate to have to replace a chain that has hardly stretched at all.
