I was thinking that as well but low mileage bike. Any suggestions what type and where to purchase?
Couple of things: mileage v age. If the chain is really old, it will suffer from internal corsion of the pins where they fit into the rollers, especially if its a standard non-oring chain. So just a little bit of running will make it wear really fast. No way around it, regardless of mileage. If the wear is uneven, then you'll have spots where the chain appears properly tensioned, then turn it thru a ways and it tightens up.
Remember alos to adjust it with weight on the bike. The wheel moves thru an arc as it goes up and down. You wnat to adjust it at the point where it is the furthest from the engine. This would be straight back and to get that you need weight on the bike.
