All iknow is rotax make cart motors too and theyre current 2 strokes, but not sure on old 4 bangers, I do remebr a post in FT re having to check the rubber belt drives all the time, but i think they go like stink, which makes me think if its not looked after and feed parts it will blow like stink, just seems the way fast stuff is ? basically i have no idea, but why not post up on the Ft forums in the tech section, those guys will be able to tell you for sure.
dont forget that one is REmote start so you will also need the driver and starter for it.
