I am looking to do a sprocket change a chain swap on my 05 zx6r. I wanted to do it myself, but had a few questions before I tear it apart. I have heard that it is easiest to just cut the stock chain with a cut off wheel to get it off. Also what size is the rear nut to loosen the axle bolt to get the rear wheel off? Is the front sprocket reverse threaded? Any help would be appreciated. Thanks
