Tim, I've a good use for the used CT125 piston/rings
I've seen the little TS50 Gaucho beasty and a deal has been struck..almost
biggest prob now is it just needs to find it's way home
main difference with the '75 model, lower shock mounts moved fwd is about it I believe. There might be more but that's the main contention
nothing drastic but the early arm doesn't fit the '75 so break out the grinder and welder if you wanna go pre'75
