Saul Posted 4 hours ago Share Posted 4 hours ago Here’s one for the brains trust. I saw this 05 Bonnie today. What’s going on with the head? There seems to be something bolted in next to the spark plug, anyone know what it’s for? I looked at a different Bonnie of the same vintage and that didn’t have it.
