Tell that guy to eat a dick, 1800 I better be able to ride that bike out of there with the front end pointed to the sky. So you know you need pipes and a clutch. We'll crunch numbers real quick. Pipes from here, 300 for a clean set, clutch (I imagine your on a budget) tusk is I think 60, coolant 10, trans fluid 10, what the fuck is your time worth?, clutch cover gasket 12.
So well say another 400. 1800+ 400= 2200. Obviously give or take a few bucks. I've seen awesome bikes go for that much. For a few hundred more you can get a really good runner.
