I am thinking about getting a Gradon rev-box,but not sure its worth the $.Do they really improve acceleration,or do they just improve top end?Is there real difference's in the curve?

 

i have woods cdi it actually advances the timing for lots more low end plus no rev limiter, i have stage 1 kit but i think just the cdi is 300.oo

 

Get it!! You wont be sorry! It really wakes that beast up.

 

I honestly can't tell the difference in acceleration between the stock CDI and the Woods CDI. Maybe if you had a stock pipe and stock jetting you might notice a difference. Until someone dynos a machine with the swapping out of the cdi being the only variable I don't think we'll really know.
The thing I do like about the Woods cdi is simply the fact that I don't hit the limiter in 1st-3rd every 2 secs like I used to, to me this was reason enough to have one.

 

RW says over revving won't hurt it. Is this true? It doesn't seem good. I want to get one, but my motor will be staying stock. At least for quite a while. Warranty.

 

i have cranked the **** out of my motor, missed gears way over rev'd it and mine still runs great

 

You have the Woods kit though don't you?

 

ya stage1

 

Here's a dyno of a 400ex, stock CDI VS after market CDI.
you be the judge, I don't know how much the timing is advanced on the aftermarket CDI

Where did you see that graydon is making a rev box?I havent been able to find it. How much did they want for it? Does it have a rev limiter?
thanks!
