O.K. The frames are broken down and ready for sanding... Notice the difference in the 2 styles of rear frames. It looks like they got rid of the chain guard in exchange for another axle bearing.
I will probably try and save the beefed up one and do what I did to my other one and slide the mount over and use a centered axle. I have a couple in case I break one. And then I will use all new parts for the rear and have it identical to my other one. I am also thinking of going with a yellow frame black seat and blue motor. Any thoughts? Randy
