Thanks for the timely suggestion AG - I just put on my new set last night and agree with you, no need to advertise for both Yamaha and Tusk as I wiz down the trail. I tried your suggestions and, sure enough, the black logo came right off, just as you said. However,I was left with a grey shadow where the logo had been and additional light to moderate applications of acetone did nothing to remove it. I was finally able to remove the shadow with a dampened Scotch pad and then I polished up the lightly scratched guard with a judicious application of rubbing and then polishing compound. Looks pretty good now but it didn't really look THAT bad before.
