That thing is pretty rad, diggin the spoked wheels.
This guy has sorta done what I have done, looks like he used a steel NSR1 swingarm and forks on his. Mine will be a little different. I have a YZ85 Aluminum swingarm I am going to hack up to make work. Or possibly some other Aluminum swingarm.
Also had a kinda inventive way to make a reed block that allows bigger reed/intake and still allows the bushing spacer block. At least on paper anyway. (edited)
