I didn't want to hack the other thread. Is this a pretty easy mod to do yourself, or is there a certain way it needs to be done. I could certainly do this myself if all ya have to do is open it up and maintain a smooth area all the way around the opening, as i have done a few sets of moto,4 wheeler heads... Please is you have expreience with this drop a line in.. Also is there anygain to doing this mod or just a (I have that done mod)

Thanks JOHN
