After KX500A 83 CDI unit and or stator to buy or lend need to hear motor running to see if any engine work is needed. Have stator, it seemed to ohm up ok but using 250 cdi and sparked only a couple of times and weak.Wiring colours are different as well so only using uneducated guess work.Some parts cross reference list say newer ones fit has any one tryed this,using later model parts.Or would you have use the whole set to get it to run?Any suggestions welcome.
