IT SAYS YOU GET A LIGHT-WEIGHT FLYWHEEL NOT JUST A BOX

Duncan sells the Vortex CDI which will change the rev limiter, and make a hotter spark. They seem to be the best CDI around. I plan on trying that out in the future. It also has 10 adjustable ignition curves that are preset for the 450R.

I have the sparks kit on mine and it is the dirtbike CDI, wiring harness, stator and flywheel the coils are the same it made a huge difference there is alot of machice work on their part to make it work though the parts will not just bolt on. They also ported the head put in the dirtbike valves. The 13.8:1 piston pipe and one of my FCR kits. It is close to the Hybird I had last year.

I will have a magnum cdi box very soon. It will increase the rev limiter by 1000 rpms. The price will be $115:)

Will it just add RPMs, or adjust the timing curve as well?

I too am curious if it just raises the rev-limiter or if it affects your power curve as well and who is it made by and where do i get it.

I spoke with Scott @ sparks today and he was very helpful. The reason they say it is for hard core racers is becase you loose your headlights. I need my headlights, because I love my night rides.:)
