Aside from things you'd check on any used motorcycle purchase (tires, brakes, signs of crash damage, rust in the gas tank, ect), the C50 doesn't have any big "fatal flaws" to watch out for, at least it shouldn't at that miles. I've encountered a couple C50/M50 bikes with the "death rattle" from the cam chain tensioners being shot, but those were all 40k+ miles. It pretty much totals the bike though, it's an engine-out job to fix, so definitely avoid if the engine sounds like rocks in a clothes dryer when it's idling. If it's got a loud exhaust, just hold a rag over the end to silence it and allow you to listen to the engine.
Fuel pumps and regulators on the older C50's are becoming a known failure point, especially if coupled with a rusty fuel tank, fuel pumps really do not like sitting around a lot and there's been a couple reports of low fuel pressure (runs like crap) caused by failed regulators. As long as the bike starts easily and runs cleanly you should be OK. The pump is readily available aftermarket, they sometimes have a habit of working for a little while after being "woken up" from storage and then failing shortly after. Good news is the pump is easy to change and not expensive if it does go south. If the tank is rusty, it may still be an OK candidate, but plan on doing some work and definitely use that to negotiate the price down.
I paid $1500 for my 2005 C50, clean title, clean bike, 12k miles, been sitting but running at time of purchase Owner was in the Army and had been out of the country for several years. Bike was not properly laid up for storage, but was kept indoors. Biggest issue was the tank was rusty, that knocked the price down from the $2200 advertised to $1500. It also needed tires and brakes.
