just my 2 cents worth on this. I just this past weekend replaced the stock bars with a set of 7/8" Renthal RC High(20mm higher). This gave me just the right amount of increase in height to stand up comfortably without having to use any bar risers. Yes you do have to either drill locator holes in the bars(not the reccomended route) or, as i did, just grind the pins off and wrap the new bars with two layers of black eletrical tape. As far as grips go; I went with Pro-Grip gels.Much better vibe isolation. Take the throttle tube to a bench grinder and simply rotate round and around until all ridges are ground smooth. I also installed a set of Acerbis Rally III hand gaurds with no problems at all. You will need to drill a hole in the end of the t/tube slightly larger than the hole in the end of the bars to get the the mounting bolt in. In all it took about an hour and a half to complete. Very happy with the results both functionally and astetically.
