This. And test ride before. I personally quit letting people test ride my bikes after one kid ran my yz125 into the side of my truck. But that's another story.
Compression test for sure. It's it looks beat to shit in person, that would make me lower what id pay depending on local market....and how bad i want it. When i bought mine, i had the guy take off a good bit because he didnt know the bore of the cylinders. Turned out to be stock bore.
