Still working on it. There are a lot of Chinese offering on Ebay that are really low priced. They list a bunch of bikes from 125's to 900's and say its fits them all. I'm not ready to go that route. I think I will buy TW kick crank assembly and a TT225 spline boss. My intention is to swap out TW long boss for the TT short boss. I hope it works. I am watching for a used TW Kicker.
