That sucks! I've always been partial to the 4-stroke engines, but respect for the 2-stroke riders. Like stated previously, you have acquired a machine that is relatively cheap to fix/maintain compared to the 4-strokes, but it sucks that this guy was such a jackass about it. If you ever need some work done, just let me know. I've been in the motorsport industry my entire life, and I know a lot of good people.
