Dynatek FS CDI for the Grizzly 700 Review

Review by: Buster

We just received our Dynatek CDIs from Dynatek. We've installed one today and the other one goes on tonight hopefull. We plan on getting some ride time in this weekend so we can provide a review of it soon.

Our initial thoughts:

- The Dynatek CDI FS appears well made and well thought out.

- All connectors are idiot proof and if following the instructions to the T, you shouldn't have any issues with the install.

- The instructions recommend but say it's not required to pull the right side plastics off for the install. In our findings, you may as well take the 2 minutes to remove the right side cover for the install as it will be a time saver in the end.

- We did notice a slight discrepency in the install instructions that required the installer to use a T-tap to the throttle position sensor. This was actually required for an earlier model and the latest model has a Y-connector so wire tapping is no longer necessary, which makes it more idiot proof. I spoke with the President of Dynatek about the instructions and he said they would get the instructions updated right away. Super nice fella, and trully sincere about wanting this to be a great product. Cutomer service from Dynatek already seems impressive!

- The quad we installed this on earlier today runs 26" ITP Mudlite XTRs which aren't a light tire, plus has full skids. Prior to the install and in high gear, just sitting straight up on the seat and slamming the throttle, would not do a full wheel-stand. After the install, using the same wheelie procedure, it did a full wheel-stand. Had we not gotten out of the gas, the quad would have come over backwards. That, in and of itself is impressive initially and hopefully implies that we'll see some great power gains on up in the power curve. But, we'll see this from fully testing.

- The new box also made our test quad start easier and idle better than stock.

- The best thing that we've found second to the power gain was that it eliminated the mid-range miss that the 700s have. They all have it, you just don't notice it with factory exhaust. After adding aftermarket exhaust, you can hear the mid-range miss at 25mph or so. However, it's gone with the Dynatek CDI. Yamaha screwed this up and Dynatek fixed it. GREAT!

Please stay tuned for a full write-up.

I was going to dyno mine with and without it to see what kinda difference there is. Where where you going to get the dyno done? Let me know and I will bring mine down.

Well, the quad is going out this afternoon for more testing on some open terrain. Unfortunately I don't have access to a dyno, wish I did.

I road yesterday a bit more and overall, it seems to me like it has more crisp throttle response than before and certainly more power off the line. My thought at this point continues to be that I'm very happy with it and we'll see how that changes (hopefully it improves) after this afternoon.

Did more testing and the initial tests went well. Again, great throttle response and that's the most impressive thing so far. I've got more testing to do before a full review and as soon as I'm done with a thorough test, a thorough review will be posted. It will probably take me a week or so to get a full test and review done as we don't have a lot of time on the weekdays.

So far, it looks like a great addition to the quad for more power.

I did not notice the annoying mid-range miss that normally occurs from 22-27MPH on mine when I road yesterday. I hadn't even thought about that until GrizzWiz asked me last night if the CDI cleared that up. I'll check it again on my next run and pay specific attention to whether it's gone or not. I will also include that in my review.

Thanks for bringing it up.

No, a fuel injection controller is just that. A CDI is an ignition controller.

And BTW, welcome to the board!

I love this thing and so do the other 700's in our group. Throttle response and low end is vastly improved and I don't know if I could do this before the Dyna but I serioulsly doubt it but I get the holeshot against my buddies brute 750 on stockers and me on 27" XTR's on 14's. I then pull him pretty hard until he hits top end and I even outweigh my buddy by 80lbs so total weight difference of tires and rider is about 160lbs. Next time I will run my stock rims and 25" Terracross. Almost forgot the most important thing which was the mid range miss which was driving me crazy cause it sounded like a machine gun set on 3 shot bursts is completely gone!!! It fixed the other 700 in our group too but the 08 never had the miss that we could tell but it is completely stock so who knows. Maybe just couldnt hear it.

You won't be disappointed, I assure you. Dynatek has done a great drop with teh release and now we can see why the release date was pushed back a few times. Obviously, more R&D before they released the final box and all we can see is all that time paid off and was worth the wait.
