I have a 1978 Honda XL175 I want to get running again. The Kick start shaft is broken, a common problem on this bike. Replacements are hard to find and usually $400 or more. Maybe I can make a few and sell a few. I am wondering if I can use 4130 steel that is pre hardened to Rockwell C32 and has 135,000 psi tensile strength. Or maybe just take a grade 8 bolt and machine it. or maybe even a metric grade 12.9 bolt which should be even stronger. Anyway I am wondering how the splines were made on the original. I could use the E head, (shaper) on my bridgeport and a rotary table. Do you think this is a good idea?
