A friend of mine just bought a kfx 400 and is considering buying a dyna cdi. I own a 700 prairie and told him even though they are expensive if his helped half as much as mine it would be a good investment. If anyone has one on a kfx or z how much power did it give you and if you would recomend buying one. Thanks for any help!!

 

I have one on order.

A lot of people say they dont notice much of a difference, a lot of others say it was a nice gain.

I read that Dyna the best, Vortex is also good. They both improve the timing curve, raise the rev limiter, have better spark. Almost all of the others are made by procom, all they do is raise the rev limiter. I have heard of the rev limiter only being raised as little as 300rpm's with a procom.

You can get a Dyna from Sweetquads (site sponsor) for $350.

 

go with the vortex, for $400 from gopartsdirect.com, it has a hanldebar switch so you can choose what setting you want to use.

 

I have the dyna on mine and what a difference it makes, vortec is good too

 

Mucky,
Ifyou had to give an educated guess about what kin of power would you say you gained?

 

I bet I gained at least 3hp
the bike was fast without it and when I got it set on the curve I liked it even had more power
