Ok, I'm a complete noob on how this would work. My stock bar end weights spin freely. How do I go about putting on some bar end mirrors if they won't even stay in place? Do I have to buy a new handlebar and 7/8 bar end weights so that I can attach them? Or do I just need to buy new bar end weights that won't move freely on the handlebars? I feel like this should be a lot easier than I'm making it. Oh yea, it's on my honda 919.
