Has anyone had this happen with their Dynatek CDI's?
I have a Dynatek on a 2002 Prairie 650 with about 1100 miles on it. The CDI was brand new and had only been in use on the atv around four hours.
After a little ride I pulled up to talk to another guy and shut the quad off, when I restarted it, it wouldn't hardly rev-up at all. I drove it back to the shed with a full throttle top speed of around 20mph, it would idle fine.
Luckily for me I had my stock CDI in the truck and put it back on and it ran fine.
I called Dynatek and the tech told me, this was a strange-one and to send it in for testing, he acted like he'd never seen this situation before. They did have a call tag for me the next day and it's now on it's way back to CA. Now I have to wait another six weeks, what a bummer!

 

I guess if you get past that 4 hour period you're alright lol. I have read several posts like that, just a few hours after installing it it fails. Why he would act like that was unusual I don't know. Mine's still working fine as it has since last September. I'm thinking about selling though, it has me scared to ride the bike, too much power for the steep hills around here [img]i/expressions/face-icon-small-smile.gif[/img] I've been climbing them in high gear to mellow it out a bit, I know its bad on the belt but so is flipping it [img]i/expressions/face-icon-small-smile.gif[/img]

 

ive had this same problem with dyna got my ignition for 04 p700 on christmas maybe had 20 minutes on original ignition when it failed sent it back in gotreplacement some time later and it failed right out of the box and am now waiting for third one. I have been following this forum for a year now and today decided to join because of my frustration with the dyna ignition! I hear so much more negative feedback on these now than positive. When i call to tell them about another failed ignition its always the same response wow that is rare that it failed sure its not the prairie because we have not had many problems with these. WHATEVER!

 

I just sent back my 3rd one today haven't gotten more then 3 hours apiece out of each.had 2 in my 650 and the 3rd in my btute 750 all the same.

 

I also have had enough. I am on my 3rd dyna cdi and have removed it do to problems.

 

It may just be bad on your atv. We tried some dyna cdi swapping and found that it would run on some atv's and not on others? On my bf750 it sounded like it was running on one cylinder, His bf was ok. Some people have been installing a second battery to try to fix the problem. Maybe one of those big marine batteries mounted on the rack would work? I'll stick with my dg5. The dyna brutes can't pull me unless we race over 65mph anyway which never happens.

Where did you purchase your DG5 cube. I'm interested in gettin either the DG5 or the dynacdi. Any info would be great.

Thanks,

Colin.

 

I got mine right from the source. DG Racing at 714-299-3865 and ask for Don. I think he is the main guy there. The customer support is done by the desining engineer that made it. They were the first company making such things to know that the BF750 cdi is different from the 700. They made the dg5 new for that reason. How does your Brute ride with the 27" tires? I am thinking about putting some bigger tires on my old stock wheels for mud riding.

 

Thanks for the info.

I put my 27 inch Gators on my stock rims. Love 'em in the mud. Larger tires are definatly the way to go with this quad. It can handle them. Can't pull the front end up like before with the stocks for now. I'm gettin a clutch kit. Ordered mine 2 days ago from dealer. (went with dalton). Stock clutching still works fine. You can still spin the tires easily. You gain a few pounds with the weight of the tires. But I think thats a good thing. Don't want that front end to come up more then it has to. Way more stable too. Tippy feeling is gone.

 

Same problem as you I purchased the dynotech CDI box for my 2002 prairie 650 and at first they sent it to the wrong address or something so I had to wait that much longer then when I finally got one I unhooked my battery unplug my original CDI plugged in the new dynotech hook the battery back up but the seat on it and when I turn the key total smoke show ruined the rear half of my wiring harness and now that I've repaired all the wiring the original CDI box won't fire I have messaged the seller on eBay where I bought the CDI of contacted eBay and I've contacted the manufacturer but so far my experience with dynatech has been horrible I was so excited to see the performance gains from the CDI but it just ruined my quad I hope they make it right
