Scotty, I don't think it will be an issue at all with the DID chain on the c-5. My yellow O ring chain is pretty fat, with good sized O rings. I think I read some where, on the forums here, they switched to somekind of black O ring chain on the C-5. My yellow ones are pretty pronounced. It would be hard not to see that they are yellow.I would say just by memory,that the yellow O rings are probably every bit as big as the O rings on the DiD chains I put on cb750's.
