How to build a chain drive spool/rear diff for crosskart. This drive spool was designed for my R1 crosskart (KJ Raycing style chassis) This is my 5th design. Made a few prototypes after working the bugs out. i came up with this design. Made for buggies with bike engines that have 100+ hp. Has held up to the 180 hp R1. Uses R1 sprocket pattern so you dont have to get custom sprockets. Next video i show how to mount to a crosskart!! STAY TUNED!
