Just finished a functional restoration on a 1981 XT250. Been sitting since 1992, original owner. Exhaust was rotted off but I found an original Supertrapp fo the old girl. Did a nice long wide open fifth gear run and shut it down. About 25 miles on the plug. Bike will likely see 'around the property' duty. Seems a touch lean but I'm inclined to leave it be. Opinions?
