CDI box on 400EX
#1
My dealer gets $129 for CDI boxes that eliminate the rev limiter. I was told a local ATV shop (Tom Miller Motorsports in Huntingdon) can take the stock box, modify it and make it like the aftermarket boxes for $90. Thats what the previous owner of my '99 400EX told me he had done. Now a guy I ride with has a '01 400EX and wants his box worked on or replaced. Does anyone know what they do to them to delete the rev limiter? Do the boxes use the spark from the coil to know what RPM it is at? It would be great if we could find out how this is done and be able to save some dollars.

Go to http://www.ctracing.com They sell the CDI hi rev ignition module for 95.00
It works very well, I have been using it for over a year and a half now. No problems....
