Ooooops! Fairly high mileage, I'm assuming the odometer is in KM which says 10k kilometers, so about 6k miles. I've been told with proper maintenance these things can last a long time, and there has already been one motor refresh (valves, etc) so I'm not worried much about the motor... it seemed to be in good working order, sounded good, no leaks, didn't look to be burning oil or smoking.
As for the kick I mentioned, yes its from a dead stop... as soon as the scoot starts rolling and the clutch engages for the first time, there is a pretty noticeable kick/jerk and then it's all smooth sailing after that. Only happens from a dead stop.
$700 seems like a decent deal, from what I've seen the clutch spring is an easy fix (<$50), belt drive a little more pricy ($100) but still not anything that would sink me.
