    No Spark 1979 GS 425

    Im working on my roommates 1979 GS 425. We took a trip to Austin then he parked it. I now have no spark at the spark plugs. I tried grounding the spark plugs against the engine casing and no blue spark appeared. I did the timing adjustment as per the manual and they seem to be dead on (before leaving for austin he had them done).

    The coils are after market and I have four wires running to them

    2 orange/white
    1 black
    1white

    The two orange/white are hot when the bike is turned on. Havent tested the other two. Whats the next step to solve this ignition nightmare?

    Thanks guys!

        Why does it never happen to me?
