    I s there different year twin cam motors that being single fire the rear plug wire goes to top coil and front to bottom plug in?

Nowadays I see more and more open electronic components. For example, this coil. The owner of this motorcycle opts not to put the chrome cover back over it, he likes to see the functioning component exposed. Problem lies, these wires sometimes come loose. Typically not while you're riding, but they will come loose, they can get kicked off as you climb on and off the motorcycle. I wanted to show you a quick way to make sure the plug wire's not only stay sealed from the environment, but also stay in place. You can remove 'em, one at a time, and again, I stress, one at a time. This particular motorcycle is single fire ignition, if you reverse the wires, it will not start. Remove 'em one at a time, use a little solvent, a light solvent cleaner. Clean the tower on the coil, apply a light coat of dielectric grease. Reinstall the plug wire. Make sure you wipe up any excess grease. And just get a tie wrap. Put the tie wrap around the spark plug boot, put it together so that it's grabbing halfway on the boot, halfway on the coil tower. Just draw it tight, again, you don't need the strangle hold on the tie wrap. Cut the rest off, and just send the connector part of the tie wrap to the back where you don't see it. Leaves you with a nice, clean finish. You can't physically pull that plug wire off the coil. Do the same thing for the top wire, the top wire goes to the front cylinder. A little light solvent cleaner. Clean up the tower on the coil. A light wipe of dielectric grease. Slide the boot back into position. And just put a tie wrap on it. Draw the tie wrap down tight. And just cut off the rest. Carefully rotate the part that the tie wrap joins in against itself. Rotate it to the back so it's outta sight. Leaves you with a nice, clean black band around the plug wire boot, and it guarantees those plug wires can't come off. Even though you're running an exposed coil. Looks real good. Now it works real good.
