As I stated in the "Running Lean "thread , I would make a new one with my findings on running a fuel optimiser on a a straight stock setup.

The Dobeck EJK showed up today, and I got to wrenching right after work. It installed fairly easy. I mounted it in the storage compartment by drilling a hole through the bottom of the plastic compartment near the fuel injector. I then put a rubber automotive grommet in the hole to make it clean and keep water and dirt out. I found that grommet at Napa for $3. Well worth it.

Now the good stuff. I put everything back together, pulled it outside and started the quad. The EJK was programmed for stage 1 modifications from the factory. As the bike was warming up, I went through the different settings and confirmed that they were correct and recorded them.

I drove around the yard for about 15 minutes making sure I hit most of the different throttle ranges. It's a night and day difference now. The motor is running a **** of alot better, the throttle response from down low doesn't have that hollow bog, the mids feel more consistent, and I really didn't get to much into the top end, but it was more responsive and had a much better sound, no more tinny noise,, but a deeper I'm not starving for fuel sound


I did put my hand in by the exhaust, its hot, but not blazing hot like it was before. This wasn't a really good ride for a test run, but I had to see what difference this would make. I'm pleased with the results so far. If I get out this weekend, I'll do a more in depth review of what all I find experience. Seems like $225 well spent at this point.

Saturday we have our annual July 4th party. I'll be doing alot of riding all day, so I'll have a really good review Sunday or Monday on here. I'm really excited to put the Kodiak up to a good hard day of riding.

As promised, here is a good review of the complete stock setup with a fuel optimiser programmed for stage 1 mods.

On Saturday, I put on about 20 miles, mostly through woods, trails, old logging roads etc. There are a lot of strip mines where we ride too. This was the first time I had the Kodiak out on a good ride with the EJK.

Everything felt better, no backfires, bogs, or feel of fuel starvation. I got the bike into all the different throttle ranges easily and could tell it was definitely more responsive.

A hill that we climb starts from a dead stop, the Kodiak accelerated right up it, and pulled hard through. Not once all day was I disappointed in buying the EJK. I really feel that without it, the Kodiak was right on the verge of being too lean. It almost feels totally correct at idle and in the mids. Up top oin the throttle range, it felt like it was just a touch rich. I wanted to ride and not tune, but it can be lowered very easily on that controller.

I'm sure I could have taken it back to Yamaha and complained, probably had them reprogram the ECU, but I wanted to get a programmer anyway, and hope that maybe this will help someone else out who had the same experience as myself. The other reason is I can tune this bike now, and no more worries.

The end result is $225 well spent to make the Kodiak a well running machine.

Your welcome boss. I enjoy trying stuff out and sharing the results, good or bad!

Got my EJK put in finally. Very easy install, just plug in play. I mounted mine on the side, inside the storage box. Haven't had a chance to hit the trails yet, just ran it around my property. The throttle response is noticeably better and the engine sounds/feels smoother throughout the rpm range. More seat time will be the true test but I'm happy with this tuner so far. Next she's getting lighter clutch weights for better take off.

man i have to do this next, this sounds like exactly what i need. having already done grizzly weights and 1.5mm shim. the hollow bog phrase really hit a nerve with me, that's what i feel everytime i try to get it to scat from a stand still. i want instant power like i know it's capable of and no backfires. wears me out. i'm doing this first chance i get. thanks guys.

You'll be pleased with the results. Let us know your results after you get it installed and go for a good ride.

Hopefully this thread keeps helping people decide on whether or not to make the investment on a controller.

Thanks for sharing your feedback, it's stuff like this why I love forums since it adds a ton of value to owning one of these.

Just added the EJK to my Kodiak today. Did not get to really test it out, but did notice a reduction of exhaust fuems the first time I started it. Seemed to have better response at the throttle. I am running the stock air filter and exhaust, so did not change any settings on the controller. Installation was very easy and I am overall please with the product.
