If your Dyna is making no power, then it has issues that need to be looked at. My Prairie will do crazy wheel stands in high and low gear with the Dyna. In drag races side by side with my brothers quad, equipped with a DG3, you can hear my motor shoot to high rev much much faster than his. If only I could get the power to the ground with some traction, I'm sure I can beat him, but with my crappy Dirt Devils, it just does massive dirt throwing burnouts and he pulls away. It's kinda funny really, if I do hookup I gotta let off or I'll be laying on my back. If it does what it normally does, he walks away with the DG3 and Bighorns. But anyway, back on topic, call Dyna and discuss it with Scott, my ignitor makes my engine rev up crazy fast, and yours should do the same. The Dyna ignition does work wonders on these motors. Expensive? Yes. Worth it? Absolutely. In my opinion, it's just plain crazy. All ya gotta do is hear the bike rev to know.

 

Ok fifthhorseman, I will put the stock tires back on so I know the feel of the bike again, put the Dyna back on and do a plug check to make sure its not running lean with the Dyna. Is it like the holeshot where you have to hit it under 5 mph for it to really work?

 

No, it makes its power immediately. The timing curve doesn't need the speed sensor to advance with the Dyna like the stock box does.

 

I would send the CDI back. They are real good about looking into these things. Mine had kick back and they fixed or replaced it. I have swapped mine back and forth and can feel a nice improvment. Not only in power but easier starting, and cooler running.
As I have posted before, I am 6' 2" @ 240 pounds and have the 26" ATR's and a WARN 3.0ci winch up front. It will not lift the front tires off the ground with the OE CDI. Now it will and runs up to top speed much stronger. I gained a few mph but that is clutch limited anyway.
There have been a few reports of no power gains and many reporrts of praise.
Send her back and let us know how it goes.

 

The EPI Red spring is actually very managable in rocks and other similar terrain if you can master manipulating your brakes to make the belt engage before moving. This will allow smooth as glass starts. The Elkas are worth every penny. I wish I put mine on two years ago. Those tires are a big power robber. Thats why I will never run any tires larger than stock size. I dont have any comments on the CDI, its best for me to be quit about that.

 

After alot of replies, searches, and holeshots up my street this afternoon I think I have this figured out. feel free to disagree. I switched back to stock wheels and tires and that for sure was the culprit. Stock w/holeshot and dyna both wheelie in high or low at will under 5mph. From the searches- it seems that the people that say its the best, didnt have the holeshot module, and the ones that did are the ones saying the increase isnt that great except in high midrange and top end. This would make since because the stock CDI without the holeshot is a night and day difference from the dyna. On a 300' stretch on pavement the dyna gave me 1mph over the holeshot module. (cant really tell by seat of the pants) but if that trend will continue with longer distance the dyna may pick up a quad length or two. The top end I cant report on yet but if it dont rain I will try it tomorrow. It does seem like the fan comes on less with the dyna though. KOD, that was a very good spring test you posted, Were there any springs that gave you any topend over the stock spring? (semi tame) I Dont think I want to have to remember to be gentle on takeoff, but will get a different primary. Thanks for all the replies guys, all the imput really helps cover all bases.

 

I never really got to test top speed with any of the springs. I honestly dont believe the primary spring will make any difference in top end with a stock to nearly stock Prairie. If you want an excellent primary spring with smooth pull outs look no further than the stock P700 primary. I believe kawi really did their homework on this spring and for the entire clutch for that matter.

 

Here are the top speed results from the Dyna: Just out of curiosity I did this in two places on pavement, one on flat and another on a long gradual hill. Same distance everytime. Speedo everytime. (GPS was dead and didnt feel like making the 20 mile trip for batteries) Stock w/holeshot on flat was 60mph and hill was 63. With the dyna flat was 63 and hill was 69. My belt did chirp at every take off so speed might get better with proper delfection. One thing that is interesting is the dyna improved top speed by 3 mph on flat but 6 mph on the slope in the same distance. So I guess the dyna really is worth it! Its not a magic box but it will give some improvement. PS the fan did not turn on all afternoon.

 

Thats great rivermud. With proper belt deflection you will be even quicker with more top end. I also agree that the CDI will increase the top end speed. Mine did that also but it still took a long time to get there. But, I never experienced the fan running any less with mine. Maybe the newer ones are better with that also.

 

are elka springs progressive springs or are they 2 different brands? Will i notice great improvement with the stock tires or just a little without stronger sidewalls. cheapest place to buy?
