Hi badazz,
Well, it may be true, but my mission with getting a new CDI box is to eliminate the early popping caused by the cheap factory box retarding about 3-4 degrees just before it hits the limiter (8500 rpm on my quad). I just want the ability to have a little over-rev when shifting, and the adjustable rev limit allows for that. I also like the idea of having 10 different power programs that can be thumbswitch activated, several for low end power, more for mid range, and several for top end power. This adds great flexability to the Predator.
I don't KNOW FOR A FACT, but I read and heard through several of the forums and shops, that the STOCK predator valve train is good for about 10,000 rpm before any floating or damage. I would not regularly rev to that myself with stock valve train, but I believe the design is strong enough for it.
I'm going to go with the Vortex CDI box as soon as finances and time permit.
Good luck,
JJ
