I recently sold my 2004 KX250F(fixed all major problems, revalved susp., fluidyne rads, PC water pump cover, and a beefier clutch). Is it wrong that I sold it to him with the absence of this piece information, it will need new valves and valve springs next time the valves need to be re-shimmed. I sold it to him for $3900 Can. ; about 1000 dollars cheaper than other comparable 2004 KX250Fs. Am i an ass?
