A friend of mines son has a 87 model kx250 for sale for 250 dollars. The only thing wrong with it is it needs a clutch and a chain according to him. From what I have heard the 87 model was an odd bird and has some parts on it that only fit that year. Is it worth getting? How hard is it to find parts for and getting it up and running? Should I stay clear? Any advice would be greatly appreciated, thank you.
