Greetings. I recently bought a 98 XR600 with standard bars and tank, I bolted on some acerbis Barkbusters and they are hitting the tank. The corner has been ground down and I've moved it up the bar as far as I can, but it still hits the tank on the left side only. The bars seem straight and beyond grinding it down further, possibly weakening it I'm out of ideas. Does this mean the bars are bent? Is this a common problem?? Thanx for any tips.
