3-piece ignition performance upgrade.

Due to extremely short supply only one 4th Gen Ignition Set allowed per customer.    Only 5 sets left in stock, then no more until mid-2022.

In proven lab test the new "Gen 4" CDI & Magneto Coil produces a whopping 5KV more available voltage than the "Gen 1", Gen 2 and the Gen 3 magneto field coils.   See pictures: 

MAX CDI and the Good Boy Coil works best with the special Monster Rotor magnet.  Read on: 

The Monster Rotor magnet has nearly twice as much flux density lines of force as compared to a standard China doll rotor magnet.    We ID the monster rotor magnet with a checkerboard pattern on the outboard side.

The "Good Boy & Red Wire MAX CDI can jump a 3/4" air gap as compared to a 3/8" to 1/2" gap for the stock standard "Old Dad", Old Son and Fat Boy versions.  OK! How so?

  • The "Gen 4 Good Boy magneto" has a 488-ohm coil with more turns of fine wire as compared to the so called "Gen 3 Fat Boy" 357-ohm coil that has larger dia. wire but with the same approx. number of turns as a Gen 2.    

  • Gen 4 Good Boy fine wire coil ohm resistance is 485 to 492 OHMs @ 80 degrees F measured with a quality digital ohm meter. 

  • It is a proven fact that the "Gen 3 Fat Boy" coil with a bigger winding dia. and measuring 330 to 357 ohms resistance does not produce any higher KV output than a standard smaller diameter coil "Gen1 & Gen 2 " with same amount of ohms resistance.    

  • The CDI with the Red spark plug wire has a larger Micro Farad Capacitor to take advantage of the increased voltage (400 V ) sent out by the "Gen 4 Good Boy" coil.    

  • The "Good Boy" magneto coil is identified by the red spool and has a date of manufacture sticker. 

  • The MAX CDI is identified by the red terminal wire and a Red boot.    Yes, it looks the same as competitor's CDI but it's not the same inside.

  • NOTE:   The CDI terminal fits the spark plug when the screw cap is removed.     See picture.

  • KV = Kilo Volts.   1KV = 1000 Volts.
