does anyone make one for the Raptor?? a hotter wire would allow you to go up in jet size.

Nology makes a great wire. I run them in my mini's and the Craptor. I have not had the same luck with their coils though (even if the ohms are matched).

How is it that a hotter plug or wire would allow you to go up in jet sizes? Does it increase power very much?

Go check out nology.com

The wire has a capacitor in it. It holds a larger coil charge then releases it as a hotter spark. Instead of a larger plug gap, this system seems to prevent a misfire when the required spark voltage goes over or near the available coil voltage.

Forgive me for not completely understanding, but I am trying to learn a little bit. What would cause or when would the required spark voltage go over the available coil voltage? Is this only applicable on a very modified machine,such as yours, or would it help a semi modded one, like mine? Thanks for the time.

Here is a very very basic nut shell spark lesson 101.

On the ignition coil, depending on the number of windings, input voltage and "dwell" time, the coil has the ability to produce a certain amount of voltage on the high tension side (caused by the electric field collapsing when the CDI or points change from on to off). That maximum voltage produced by the coil is called the "available voltage." If your engine requires more voltage than the coil has available to produce, there will not be a spark. That is a misfire.

On an engine, things such as a large spark plug gap, high cylinder pressures and a lean fuel/air mixture can all cause the "required" voltage to rise. It it goes too high, you get that misfire. In some cases, the electricity, being generally lazy, will seek out the least path of resistance. If your plug wire, boot or other component is an easier path than the gap in the plug, you will again have a misfire. In some cases, your engine may run fine without any load in place; however, when you put it under load (high cyl pressure, lean, etc.) that weak plug wire can cause the misfire. You can experience these problems on any machine stock or modified.

The Nology wire helps the coil produce a nice hot spark.
