Take the end plates off, 3mm Allen if memory serves. Slip a small flat blade under the left grip and shoot some WD-40 in there and twist it off. The throttle grip will slide off along with the throttle housing. If you cover the tank with a blanket you can pull the left grip, remove the riser caps and then slip the throttle off as you move the bars to the left so you won't have muck with the throttle cables. No blanket and you're almost guaranteed to scar the tank...
