Well I was extremely happy with selling my blaster this morning for $1100 when I only put $800 into it! Unfortunately, about a half hour ago the guy calls me and says the bike blew up on him. I built/fixed up this bike and I know it was very solid. The way he started it up cold and then actually floored it all the way while in neutral (and cold) scared me. I almost said something but I figured if he was going to buy it, what do I care. Anyway he called me and said he wants another 150$ to buy a new piston so he can fix it. The dude and his friend were both a couple of nut jobs and I'm not sure how to respond? Any help thanks!
