As far as the chain and sprockets, I'd replace them. For me it speaks more to good routine maintenance. If I'm looking at a bike that needs tires, and a chain and sprockets, I'm wondering "What else does it need?" and "If the guy is too cheap to do the basic stuff, did he ever check valves, change the oil, check the screens, flush coolant?"
I think the tires are easily explainable, but the basic maintenance is not.
I would see needing a chain and sprockets just like needing tires. --- A perfect chance to choose the gear ratio I want. Getting it super clean goes a long way in making the buyer thinking you respect and take care of the bike. Personally, I love getting a good deal on a bike that needs some work and tearing it down to check/fix everything day 1... when I'm done the bike is reborn as MY BIKE..
