Thanks for the nice comments!
Yes, the 125 is fairly clean, and its not missing any part as of yet that I'm aware of. There is wear in the steering spindles, and I replaced the front axle pivot pin that was worn quit well. I then squeezed the frame's c-channel together, and it all tightened up nice.
I noticed the 125 was missing the shims that go between the back of the front rims and spindle, and tossed in a used set of those I had for the 3/4" diameter which also removed some play!
I was rather relieved on seeing the minimal wear on the drive hub. If I had to guess, the hub is worn around .030", at best. The drive pin was really worn, and knowing that its a solid, harden pin, I replaced that as well. I then sandblasted the drive line and fan, and painted it.
Allen, for me, the 125 can take a while to go through, top to bottom! Keeps me busy and at home, ha!
