I'm ready to but a rev box on my 2003 Z 400 .and i have noticed that there are several to choose from. are the adjustable ones worth the extra $$$$$ or would i even know the diff.?
I only trail ride but I'm tired of that limiter kicking in when i know that it should rev alot higher .
what have you done and would you do it again?

 

I have the dyna cdi and I think its worth every penny i've spent on it

 

Go with the vortex its more then the rest but its adjustable and the best on the market. I dident think it would be that big of a difference until I tried it. I will never buy another black box again.

 

I have the programable CDI on both the yfz and the DS 730 i can really tell the diff. i can set the reeve and everything else that a CDI box controls

 

IMO dyna and vortex are the best. They also cost the most. If I could do it over I would have got the dyna non-adjustanle version, because I hardly ever change mine.

 

then what setting do you keep it on ?
i notice that you run a pipe and a hot cam .what kind of power does that give you?
