someone gave me a couple of old wheelchairs today and after looking at them a bit i've decided to have a little bizarre fun. i have a cb500t motor that is in neeed of a total rebuild so i was thinking i'd rebuilt that 500t motor and wedge it into the modified wheelchair. my wife, of course, thinks i'm totally stupid but after i finish the 750k (by the end of the weekend i hope) i wont have a project so i thought something totally dangerous, frivolous and dumb was in order. first question is, will internals from a 450 fit the 500 cases? this motor was left outside for like 10 years so it's all rusted to hell inside.
