    83 450ed ignition problem need help

    I just got an 83 gs450ed from a friend before he went to iraq. when I first tried to strat it I had no spark on either cylinder so I was instructed by a cycle shop to replace the igniter. Which I did ($125 non returnable). The bike started up the first time I turned it over but it was only running on one cylinder. I can take the coil power wires off and switch sides and the spark switchs sides. so the coils are good. Does this mean my CDI is bad if so where can I get one, and wher can I get a Dyna ignition, price, difficulty of installation.

    If you are taking off the power leads on the coils and swapping it then you are missing power on one of the leads. Check that both coils have battery voltage to them.

      The ignitor is the ignition system. Your bike does not have CDI.

      Did you buy a new ignitor from the cycle shop, or did you buy a 2nd hand one from ebay or?

      Check the voltage on the power supply wires to both coils. It may be nothing more complicated than having a faulty power supply wire on one coil. You can wire a "Y" into the good power lead to power both coils if one wire shows to be dead.

        I have power to each coil yet still only one sparks. I bought the ignitor second hand. Could one part of the ignitor be burned out? What about that Dyna ignition good? bad? can not be done? won't help?
