He is asking way to much money. You can find a brand new bike for $1000 less than that. If he included the trailer, and had some extras, a bike with that many miles, maybe $6000 if not less. I wouldn't pay that much at all.
Now for cons, it does run at really high RPMs, but there are mods to take care of that, and that is really not a problem until you hit the interstate and wanna run and 80mph. I like the small back highways, so not really a problem for me most of the time.
Lots of little noises, nothing to really worry about, just the way the bike is...i put on some V&H pipes and I can't hear them anymore. The stock seat, if it is still stock is really uncomfortable. I invested in a Mustang touring seat soon after getting the bike home.
Overall, the pros outweight the cons, and there are ways to take care of all the cons....JUST DON't PAY THAT MUCH FOR IT.
