First, I have done this a few years back and worked very nice on a two stroke road bike i used to race. What do you guys think? I know it is bad for the pipe as dirt wil get in under it and that it wil become wet and and and...but, does it work? I know how it works but on a motocross bike? Second, and more important, how do you do it? We used to wrap and then use locking wire to secure. Only the header or only the middle part? Can't seem to find anything on how to wrap it, only how it works..... I am currently using it as a supermoto and some basic motocross for motard practise.
