So, a friend's stepfather is selling his former toy... Kawasaki KZ400 "ran when I parked it in the garage 23 years ago". I think he'd be happy to have someone who would make it a ridden runner again, and is willing to take any semi-reasonable offer. What should I look for/check for? Obviously, the engine has to be non-seized, maybe try to turn it over, but after that long the carbs are likely to be thrashed. Features to check for? Worth anything at all? This is sort of a project thing, I'm not expecting awesome transportation from it, I have my wee-strom for that, but my wife's been militating for a new motorcycle, and I'm wondering whether this might be a reasonable thing for the right price. So... what's a right enough price to make it worthwhile?
