Dyna Spark Plug Wires can pop off

[thessler3]

The Dyna spark plug leads as provided with the full Dyna S kit can pop up off the spark plugs slightly. They will appear to be on, but are not making good metal-to-metal contact. The bike runs, but roughly. Push them down that last 1/4 inch carefully to make sure they are fully seated. This happened to me twice within a week. I use NGK plugs that are a tight fit in the spark plug wire caps. Previously I used NGK racing solid spark plug wires & caps and did not experience this problem. So, if your bike suddenly starts running roughly, check the plug wire caps to see if they are fully seated. Overall, the Dyna ignition really helped my 750GT run a lot better.
