^^^^^^^^ that is so dirt cheap, and assuming it is not actually bent i'd have it. the bars will be stuffed but they'd be the first thing i'd change anyway. they look so much better with no back guard anyway, mines long gone. theres plenty of aftermarket pipes that improve the running and look better too, supertrapps are great, look like a scaled down version of stock and tuneable
dunno about turning it into a café, though there are aftermarket frames to turn them into a full on sportsbike with all the correct geometry and such
there is also, somewhere out there, a monster sized trailmax which could be the scariest bike in the world, 120+ HP on knobby tyres in the dirt, i'd try it but you'd want to be wearing brown trousers in anticipation. I've also seen CB900 and Z1300 trailbikes
