I got myself a set of Hammer Head axel blocks for my 2012 YZ450 and the right hand block seems to be too thick, i cant get the nut to thread on enough. The Hammer Head block is 4.5mm (3/16") thicker than the origional. Has anybody else had this problem ? I hope the picks below can explain. Thickness comparison. With origional washer and nut. With a nylon washer that i made.
