I just recieved my powerbronze undertail for my 01 929. problem is, the instructions provided are as useless as power steering on a bike. i need help, has anybody used this undertail? or has anybody got any i dea on how to fit one up? i'm thinking just cut the original and place the new one over the top. would this be the way? any help is greatly appreciated, i've waited two months for it to arrive and i really want to see my money and patience rewarded when i look at the back of my bike
