Did a search on this subject, lots of warnings/info on special mounting kits required for Pro Taper bars, but none are really clear on if the special kit is required for the PT 7/8 bar or just the 1/1/8 oversize bar I've got a set of Acerbis guards leftover from my DRZ400. I'd like to slap them onto my 2004 WR450F, but before I carve up a perfectly good set of grips, I want to be sure that they will indeed mount up. I have all the mounting hardware with them that came of a set of 7/8 Answer Alumilite bars. Can I mount the same hardware directly onto my 7/8 Pro Tapers on my WR, or is there some kind of "taper" at the end that will prevent them from mounting up? Any advice/experience would be appreciated before I start hacking away on the grips and throttle tube. Thanks!
