Amr stage 3 rev box?

[z400mayhem]

Am i able to put on a AMR stage 3 rev box on my stock 400ex? It has nothing done to it.. Will this screw up my motor ? It says it deletes the rev limiter.. This wont blow my engine up will it?

It wont hurt anything unless you decide to run it wide open for a few miles. I would not recommend buying one though, as the 400ex doesnt make any sort of usable power up at that high of rpm range to need anything higher than the stock limit. Although it is up to you, it will work fine though. steve

The only reason I could see getting a CDI (on a 400EX) is for a beefy motor in racing conditions so that you don't need to shift into another gear where you might not be able to muster the torque out in X gear.

You'll get the same increase from a Lo-Hi Flux capacitor, New Muffler bearings, or High Temp Blinker fluid. Save your money !!!!

I've said it 10000 times, rev boxes are a waste of money. Look at my sig, I have nearly every mod known to the 400ex, except the rev box and for good reason.
