Well so far only thing I have is the 89 500, I picked it up for $120 and the engine has good compression and spark in the process of getting new carb for it to verify that it was worth the buy. It being my first conversion I'm not a 100% where I am going to start other then I know I need frame rails the roller frame and a cr500 pipe to modify other then that I've seen people cut and use the same engine mounts so idk if that way is better or just to build new mounts completely.
