Dynatek Dyna FS CDI for the Grizzly 700 Review

Dynatek Dyna FS CDI for the Grizzly 700 Review

Performance! This is something the majority of ATV enthusiasts share in common. We strive for better performance out of our ATV’s. We all want it and we all want to know how to achieve a top performing machine.

A little over a year ago I sought out on a quest to increase the performance on my Yamaha Grizzly 700. I equipped it with a better flowing exhaust and air filter. This had required me to install an aftermarket EFI fuel controller as well. All this entire combination created and exceptional performing machine but there was definitely room for improvement. It was much quicker off the line and mid and top end gains were great as well. However it still lacked something and the newly added accessories exposed some flaws in the Yamaha Grizzly 700’s EFI / Ignition system map. Throttle response was just not what I would have expected with the aftermarket performance add-ons. Plus, when the aftermarket exhaust was installed, a “mid-range miss” was very pronounced.

It seemed that this miss was haunting a lot of 700 Grizzly Owners who did similar exhaust upgrades. It was such a mysterious anomaly that even Yamaha hadn’t heard of any complaints. It seemed as if it was there on all of the Grizzly 700s, but was only audible when an after-market exhaust, or even a “power tip” was put on the factory muffler. Generally speaking, most people notice this miss somewhere between 20 and 30 mph. Well it didn’t appear to be hurting anything (other than performance), but was basically just an annoyance. So, without the support from Yamaha on the issue, we were forced to live with it. On top of the miss, it seemed that the Grizzly 700 lacked just a little on the power side.

Well, that was until a company in Glendora California answered our call. Dynatek! The new fix for everything was brought to my attention by one of the Review Crew members who said this is something we need to look into.

I called Dynatek and began getting as much information on the system they had developed. Everything they had to say sounded very interesting and almost too good to be true sometimes as apprehension began to set in that this could be another black box of “Voodoo Magic”. But, the little angel or inside me kept saying “More speed!”, “More power!” And I knew of Dynatek’s long standing, great record in aftermarket performance coils, fuel controllers and ignition systems from my sport bike and Harley Davidson days.

Dynatek customer service was extraordinary. They managed to accurately answer all of my questions and addressed all of my needs very professionally. In fact, they seemed very passionate about this. Well….That was enough for me. It was time to test this thing for myself.
The units arrived very quickly and packaging was perfect. They even included a few decals for us as well. Quick inspection of the unit and the instruction showed me that this was going to be a breeze to install. Unfortunately this was the first hitch. The instructions that accompanied the FS ignition did not match very well. But, the good news is that the connectors would only go on one way. There were a few other discrepancies to the installation instruction of the Dynatek. A quick call to Dynatek’s tech support was able to clear this up. I will not go into the details since Dynatek is most likely re-writing installation instruction as I type this review.

Installation took me about 45 minutes total start to finish. After making a few “sanity checks” and re-connection of the battery it was time for a first test. 5-4-3-2-1….Ignition! So far so good! I turned the ignition key on and with a clamp on amp meter to note any extraordinary current spike that may be indicative to a short. Now it was on to pushing the start button. As the Grizzlies’ spark plug ignited a mixture of fuel and air the 700 Grizzly roared to life and with amazement the first thing I noticed was how smooth the idle was. This was something I had not had the privilege to experience since I began the exhaust and air box mods. The Grizzly 700 always in my opinion had a slight stumble during idle. But, now, after installing the Dynatek CDI box, idle is smooth, throttle response is immediate, and the power band is as smooth and crisp as you would expect from a fuel injected machine. On top of all that, Yamaha’s mid-range miss was eliminated.
Without hesitation I quickly donned my helmet and took it for a spin in my back yard. Wow! I could not help but notice the immediate throttle response that the Dynatek FS Ignition delivered. Just for giggles, I lined it up in my yard just right so I could see if I could get the 700 Grizzly to bring the wheels off the ground in high range again. I positioned myself in a normal riding posture, made sure everything in my path way was clear and safe. I quickly stabbed the throttle till it bottomed up and the front wheels began to rise and kept rising. I let off the throttle and was astonished at the bottom end gain I had just gotten back.

Now, more excited than a 4 year old waking up on Christmas morning, I could not wait to get to try this thing on the trails. It was now off to the Hatfield and McCoy ATV trails located in Southern WV. Here I decided I was going to throw everything I could think at this little black box made by Dynatek. Steep mountains, fast straight trails, and lots of mud holes.

We began testing the Ignition system on a semi mudded Yamaha Grizzly 700. Acceleration was quick and snappy at all levels of the power band. I suddenly felt a burning sensation in my forearms. I was developing a workout trying to hold onto the Grizzly 700 now. The only other times I had felt this sensation was when I had ridden some of the Big Bore v-twins on the market. When approaching mud holes that were slightly below certain uphill grades, a punch of the throttle would cause the Grizzly to rare up on its rear wheels and wheelie right across these mud puddles. On the straight haul roads I could quickly reach safe operating speed and beyond without any problems. I won’t go into how fast I consider a safe riding speed, t I think its fast enough for me while others say it's too fast.
My seat of the pants dyno told me that this little black box that I labeled as “voodoo” wasn’t magic as all. It was a true performance upgrade, which had made more overall improvement than any performance upgrade to date.

In hindsight I really think the Dynatek CDI is a great add-on. After comparing the before and after performance I could not do with out one of these. Smooth idle and acceleration and spectacular overall performance make the Dynatek CDI a top of the line performance add on for the Yamaha Grizzly 700.

Re: Dynatek Dyna FS CDI for the Grizzly 700 Review

That's a great write-up Grizz .... before I really got on any forums, I bought a Hauck Power Sports CDI ... it made a difference on my 660 ... I think ... anyway, since then, I've read a lot about Dynatek .... and have been think'in of try'in one on my 660 to see if it will give me any "more" than the one I have.

Anyway, again, great write-up .... makes me wanta spend money I don't have

Later ....

I am guessing it will not help. Just like on a car, you can only advance the timing so much before it does harm or decreases HP.

Hey Grizz, great to hear.

One question.

Why do you think that the CDI will not help on a 660? Is it because it is not fuel injected? My 660 is lacking throttle response and i would love to find something i can do to improve my throttle response. i was thinking of trying the dyna FS non programmable but have heard many say it will not help. Can you explain why it helped the 700 but not likely to help the 660?

Thank you


Conrad

TheGrizz was replying to Gunny who stated he had a Hauck Powersporrts CDI on his 660 now and wondered if the Dyna Tek would be of more benefit than the Hauck Powersports CDI he already has. The Grizz said no because they both do the same thing - advance the timing about two degrees.

You might like running an aftermarket CDI. Gunny said he liked the Hauck Powersports CDI he put on his. Re-read Gunny's post.
