I can't remember how many miles it had, but it was probably around 15,000? Not a lot in my opinion.
Yes, change the chain and the tensioner if your timing has slipped. Before you order parts, pull the right side cover off and check the gear on the crankshaft.

It must have been shortly before that I noticed a lack of power for the first time. I credited the high mileage, but as it turns out now, it could have been the timing of the cams. As soon as I got a new cam chain I can tell if full power is regained.
