Topic: What can cause a Cam to go bad?

[Burke]

I was looking at a bike yesterday (71' CB500), and he mentioned his buddy had a 79' CB650 for sale as well. The guy with the CB650 called me and we talked. He bought the bike, had a bad cam, and he did get a replacement engine for it, but never put it in.

Im thinking that if a cam goes bad it is just a because something else is not working correctly, right?

Not that it matters if he has another engine, but I would still like know what makes a cam go bad.

Bad oil from infrequent oil changes, or, an oiling problem. I'm not familiar with CB650 to comment further. Either bad oil or lack of oil.

Thats my line of thought as well.

Q: What can cause a Cam to go bad?

A: Peer pressure?

 




Sorry, I'll shut up now and let people who know anything about 650s speak.

I would add: frequent cold starts, maybe performed the wrong way (high revs before oil is up there).
