Yeah man they're hard to find. I found one locally here too last year. It was beat with a locked up motor, but unfortunately the guy knew what he had. Wouldn't budge on 2k. It's sad, but from the guys I've seen on the web, that's about par for the course. There are a lot of guys building K0 replicas which in all honesty is a better bike considering the 5 speed later model transmission and different compression on the cam. You could possibly find the tank (I see them occasionally) and a CL front wheel. I know David Silver sells repop cigar mufflers. Could have a nice bike that runs perfectly for the price of a complete POS K0.
But then, it wouldn't be a K0!
