Hi all, I've scoured the CB400 threads here and on Google and am still a little unsure of what I'm doing, so I'd appreciate any and all help. Here are the mirrors I bought (just cheapies from ebay) and here are my bar ends: So I can't thread the mirrors into the bars because they're not really hollow (this is a 2015 CB400). I tried taking all the metal pieces off the mirror (as in the photo) and just screwing it straight into the bar (had to use the stock bolts as the ones that came with the mirrors were too thick) but this was a problem on the throttle side as the mirror would rotate with it. My other option is to bolt the mirrors on to the end of the pre existing bar ends (would have to buy longer thread bolts) but I'd rather my bike not be that wide. Any other ideas? I'd appreciate any help because this is driving me nuts.
