That's a good idea, but I think I have found an answer. First of all, I remeasured my bars, and they are the standard 7/8" (don't know what the hell happened the first time). So I think I'll go with the CRG Blindsight mirror on the left side. I can squeeze the rubber grip in enough to clamp on the mounting bracket. Then I'll secure it with my stock bar ends (does anyone building a streetfighter use em?) or with a shorter 6mm bolt and a washer (for looks and just to make sure the thing stays on). I found a set of mirrors that are attached to bar ends (Oberon); I could drill out the bars and use the collet mounts they come with, but this would be more work and they are more expensive. I'll save that for my next project, which won't be a Kanatuna.
