That is cool just curious, I would have to agree that the theory makes sense, but I still have to stock flywheel. I asked about doing one and was told unless the bike is just a shooter then might not want to do it. So I was curious what your experience has been with it. I originally wanted to do the WR kit, but decided to take it to a builder and let them handle it. I am also thinking about going bigger now, it is like crack just keeps you wanting more!!!!
