Is this an FYI or are you offering a build service or finished parts?

Your jackshaft has a 3/16 keyway NOT a 1/4" for the simple reason the driven has a 3/16" keyway and that is how they are broached. The BKS karts was one of the best single seater back yard go karts made. Another suggestion on drilling the shaft for the roll pins. It is best to drill into the keyway so the key cannot work it way out or put a washer there because keys tend to walk over time since they get compressed. The set screw on the sprocket will hold the key for a while but they vibrate lose over time. Have made that mistake and we learn from out mistakes. Did a good job on the fabrication.
