    No ballast resistor with 3 ohm coils. Yes, the price has increased just like everything else. Used to be $125.

      XJ4Ever.com offers a complete Dyna Coil kit for the XS1100. It comes with detailed instructions, coils, wires (in choice of color), caps and all of the new brackets and hardware you need. I did the job on my bike in 30 minutes from start to finish! A few years out, I couldn't be happier.
      If you think you can save a few bucks running back and forth to the hardware store, then do that instead.

        Ok so now to my question-what would cause the #4 cylinder to not get hot? Coil was replaced but not hot like the others. Is this a fuel issue? Is this a pickup coil issue? #1 pipe is hot like 2 and 3. One thing I did after a ride which seemed normal-I as per photo above adjusted #4 float to 23 mm. If float level was not correct-would that cause this cylinder to not get hot?

          My guess is the pilot jet is probably clogged up with ethanol residue. If the bike isn't ridden much, this is likely to happen.

          Lucas Safeguard Ethanol Fuel Conditioner Review: If you run E10 or worse in your vintage motorcycle, this will protect its fuel system.

              Since my Jeep is in the shop for issues I ordered 2 pilot jets just in case I need them. Genuine Yamaha.

                So I got the jets today from Partszilla-very small-says 42.5 on it and no holes in the side-did they send me wrong part?
