    '86 Honda 350x. Weak spark.

    Thank you for this forum.

    My '86 350 x has been a real trial. Now it seems as though the spark is very weak. The bike ran great last week, very hard to start though. I do not want to just start replacing electrical parts at random hoping for the fix. Would welcome feedback and direction. Thnx.

    Unscrew the spark plug cap from the coil wire (yes it will unscrew), snip 1/2" of the wire off, screw plug cap back on.
