1. Stop believing what sellers tell you.
2. When I get a phone call and someone wants to start negotiating a price I usually know they aren't for real or most likely won't even show up. Because what kind of person negotiates the price without even seeing it. Usually these people are dreamers or tire kickers. To physically pick up the bike you need to go to it anyways. It really logically doesn't make sense. No offense but when I hear that I just say sorry I don't negotiate over the phone. They never come to see it. You can probably understand if you feel about the seller's position. You called and negotiated a price, came by, test drove it, then left without the bike. I don't mean to be rude at all but this is kind of just rude.
3. The KZ conveniently doesn't run. This could be for any reason. The seller has claimed this is because of a dead battery. To you this is simply a "non runner" and you may or may not be able to diagnose in person. Stop believing what sellers tell you.
4. The person who said to not hold your breath on selling the fairing is very correct. It's not really worth anything, and it's pretty much impossible to ship cost effectively.
5. Stop believing what sellers tell you. You acknowledge seller has said X. Your assessment of the bike is completely independent of what he said. If you can easily identify that X is untrue then you have potentially identified them as deceitful.
6. The 650 seems like a runner. It's not a very popular bike and they don't really have the value of the other four cylinders, but you're going to chop it up anyways, so it doesn't matter.
7. P.S. I guarantee you that turn signal isn't the only thing that will need servicing. Start by checking the date on the tires.
