Agreed Selector. I offer anyone to go on any dirtbike site and see how many Wr450 owners have done the mod. I personally know of two Wr's with NO problems from this mod. Its done all the time without any problems. Motorcycles,atv,automobiles.......they're all made on an assembly line. Your bound to have a error or flaw in a part from time to time. Its just numbers and odds guys. Not all quads are identical.
