i just picked up what i believe to be a 1980-1986 kdx 200 or 250, how do you tell?, not exactly sure on the year model.... it has sat in a barn for years... spark plug out, and carb off... the kick starter still moves smothly, the piston moves smoothly, its not locked up... i was planning on either reasmbling the carb that i found next to the bike or buying a new one, spraying some carb cleaner in the spark plug hole, like 2 cans worth and moving the kick starter to flush out the top end.... b4 the carb is on of course... from just visual inspection it looks like i need a new carb (maybe) a throttle grip... and a seat, the rest looks ok other than the plastic... any tips would be greatly appreciated, i know this is vague but i just picked up the bike
