400 ex rev unlimiter


Recommended Posts

I recentally purchased a 2001 400ex, I have no idea if it's stock or not <_< . I was wondering if there is such thing as a rev unlimiter, if so how do I tell if it has one? I have had many people tell me it's real and many telling me that there is no such thing. :blink: Can you guys help me out on this? :(

It's an aftermarket CDI that replaces the stock one. Gives ya an extra 1000 RPMs over stock. You'll know if u have one...

I've never owned a 400 ex so I don't know if I have one... I never riden a stock one to know the difference in power. <_<

all the people and builders around here will tell yah it's a waste of time. they don't give any extra power

If you've ever riden an EX without and with one... you wouldnt be saying that.

 

Duner- on the stock EX(OE CDI box) it feels the like the engines cutting out way to early. the aftemarket box gives ya a little more up top.

 

 

It's kinda like a banshee with stock pipes Vs. one with aftermarket pipes...
