hello I drive an er6n, is my first “season” and would have a question for knee grinding. my grinder looks like this at the moment (http://imageshack.us/photo/my-images/9/snapshot2011072311.jpg/ ). as you see it is not evenly sanded, but the front edge is sanded off (with my left grinder this is even more visible, as I am not yet so sure on the left and not so often grind). now my question is whether I have something wrong with the hang off technique. do and what I can do so that I (as I have seen with other drivers) grind so that my knee grinder is evenly sanded off. is it because my motorcycle is not a super sportsman and therefore I automatically do not come so far down? of course I don’t care how the grinders look and I know that the question is a bit banal but I would still like to know if this is “normal”. thx, mike
