The 07 are known to make noise in the primary cover when up to temp. It is most noticeable when in neutral and the clutch lever is released (clutch engaged). The cause is the torque compensator. If this is the noise, not an issue. Can be fixed, but causes creep when in gear and clutch lever pulled. Really not an issue. As for price, its too high. Is it worth that much? Only if it has all new rubber parts (hoses, throttle body adapter, vacuum caps, clutch cable, tires, etc). As is a good price is about 5000-5500. Low miles aren't really an issue, but low miles bikes aren't always a great find because you might have to replace parts from it sitting too long. I'd say take it at 5500 if its what you want. 07 Kingpin is one of the best if not the best bike made by Victory. Every person I've spoke to that had one and "traded up" has said they wish they had kept the KP, and know several that went back after having a Cross Country. Specific things to look at:
1. Tires. Don't want anything with a date code more than three years old. If original tires, they need to be replaced regardless of miles.
2. Throttle body adapter. Under tank between air box and intake tubes. If cracked, will run like crap. Easy swap though, and something that has to be done periodically anyway.
3. Fuel lines. Don't want a dry-rotted fuel line leaking over a hot engine between your legs. GOODNESS GRACIOUS GREAT BALLS ON FIRE!
4. Break lines. Same scenario as the fuel lines, but you want be able to stop if your crotch gets too hot.
5. Clutch cable. Check it at the handle to see if it is frayed any. If so, needs to be replaced. Known issue for the clutch cable to snap at the handle because of burrs left over from the milling process. File them down and keep it lubed.
6. How fresh is the gas? Biggest issue with low miles older bikes is they sat a lot and gas turned to crap.
That's really it. And none are deal breakers. Great bike.
