i just purchased a 1971 yamaha dt250 from a hillbilly at work. it started right up in the parking lot, and seemed to have good compression. after taking it apart and cleaning it i inspected it for hillbilly welds and other parts that weren't original. everything seemed pretty solid, so i proceded to paint the frame. what i'm replacing is: carb parts/gaskets, sprockets, chain, clutch/throttle cables, tires, misc fasteners, and foot pegs. the seat foam is in ok condition so im just recovering it with a little help from mom. in the end..(by sunday 7/31/06) i hope to have a strong running safe little bike for my dad to ride around at the tracks and riding parks we go to. thus far i have $204.88 invested and still have above parts to purchase. it is my belief that all can be accomplished for under $500.00. any advice or comments/questions would be appreciated.
