4th Generation High Performance Ignition upgrade.
3-piece ignition performance upgrade.
New shipment of 200 sets due to arrive in 3 weeks.
HISTORY: In proven lab test the new "Gen 4" HP CDI & Magnum Magneto Coil produces a whopping 5KV more available voltage than the stock "Gen 1", Gen 2 and the Gen 3 magneto field coils. See pictures:
The HP CDI and the Magnum Fat Coil works best with the special Magnum Rotor magnet. Read on:
More power in = more power out: The Monster Rotor magnet has nearly twice as much flux density lines of force as compared to a standard China doll rotor magnet. We mark the magnum rotor magnet with a Checkerboard Plaid pattern on the outboard side for quick ID.

The "Mag Coil and HP 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 Magnum magneto" has a 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 stock Gen 2.
Gen 4 Magnum fine wire coil ohm has resistance of 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 Magnum" coil.
The "Good Boy" magneto coil is identified by the red spool and has a date of manufacture sticker. Recently we have seen red spools on other coils that are not the same specs as ours.
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.
