I have a guy's bike on my lift to fix a compression issue, hope it's just a valve with carbon on it. It's a '77 w/ 45k miles on it, build date of 7/76. As I looked it over and prepared to set up for leakdown testing, there's this "thing" in the way of the alternator bolt cover. I had never seen a kickstart socket, I thought they were only on 75 & 76. Engine number is Gl1-600405. Frame number Gl1 3001376. Maybe they were using up leftover parts. Combined with the Lester wheels and overall good condition, I'm going to tell this guy to call me first if he ever wants to part with it.
