Sent an e-mail regarding bar riser construction and universal-ity. I started this thread a few years ago because I wanted to make ones with rubber bushing dampeners. But now that my XT has those built in already, I'm not as concerned with that feature. But just for the hell of it, "How are Rox Risers Constructed?": http://advrider.com/forums/showthread.php?t=480809
I hear that those bar end weights they sell for $80 work really well. They are mounted inside the bars with a weight suspended on a spring steel rod to create a counter-vibrating object that is out of phase with the vibes coming in, thereby cangcelling the vibes out altogether. Hey, you could probably make that too! Just need to make 'em with a threaded hole so bark busters can also be fitted.
Anyway, looking forward to your next machining adventure: 2" bar risers!!
