Hi Trent. Sorry for the delay, I have not been on my (old school) computer for a while. There are numerous parts sources. Try checking out the Vintage Japanese Motorcycle Club for starters. The leg shield on my CM91 was a kit offered from the Honda Customs Group in the late '60's. The bike is kick start only. As for the tranny being stuck in a gear you will need to rebuild the motor & see what else needs to be done. I bought my Honda fully restored. I have done restores & resto-mods before but I am not a mechanic (wish I was). These little Hondas are bulletproof once you get them into shape. Good luck with your project.
