If its lived in a salty envrionment def look at the perches. Prob is the metal is hidden from view by undercoating to protect it and looking damages it.

GP's are the primary problem. You've prob read about nagging fuel line leaks. Not a big issue, just a maint item.

Valves are hydraulic.

I've yet to hear of anyone having chain problems. Is supposedly not under the same tension as were 617 chains and therefore subject to less stretch. It is a double row chain like the older models.

With the miles $6,500 would seem fair; I'd expect that is the range I'd get for mine. At a quarter million miles it gets hard to say they are in showroom condition.....

ps: I wouldnt hesitate to jump in mine and drive coast to coast tomorrow. Mines yet to drip a drop of any type of fluid (other than D2 at an oring).
