I am trying to adjust the CO on my 06 Attack because I have a bad bog right off the start, even while the sled is not moving. If I hit the throttle it will bog (even with out the clutches engaging, so it's not the clutching) From some of the posts I have read it sound like I should trying to adjust the CO setting. I follow the instructions that are provided in the ty tech pages but can't get it to work. I can enter the diognostics setting and get the "dl" image, but when I try to toggle to the "CO" setting with the select botton, nothing happens. It stays in the "dl" setting. I am following the instructions. I can't figure out what I am doing wrong.
 
Cancel the above post, I found out that I wasn't getting a good enough ground when I was grounding out the green wire.
 
Did your figure out what your CO #'s are?

Each cylinder said 0 so I bumped them up to 10 like the instructions said. Still has a bit of a bog though. It seemed to help a bit. Don't know if it is my imagination or not. What should they say?
 
I checked my CO #'s last year they were all 0's! I believe they come from the factory with 0's on all cylinders. I had no issues with bog but decided to jump the #'s to 5 on all cylinders. Went for a rip noticed no difference so i put them back to 0. This season i might try going to -5 see what that does. I find them to be alittle rich anyways. Sounds like you may have another issue. Airbox lid on properly??
 
The screens are inside the injectors. You have to pull the injectors. Hook a battery to them. 9v should do it. Then spray carb cleaner through both ends. Use an air gun and blow through both directions. Also don't leave them charged with power for very long. We've had to do this at the shop with injectors that just wouldn't clean out on their own.
Be careful how much you turn your co up. It will start running to rich on excel. I played with my uncles grizzly 700 and it made a seat of the pants difference. But it also ran to rich on excel so I had to back it down some.
 
Because an injector is closed until it receives power then it opens up to allow fuel through. So you need to power them up to blow through them and clean the gum out.
 
Just woundering if we use some of the "Fuel Med" or likely the "Engine Med" products yamaha is offering this year as a preventative mantainance thing.....thats what they reccommend.
 
Hey stomper have you replaced your exhaust donuts yet? if you haven't try blocking your exhaust off with gloves on your hands your sled should die with in a couple of seconds if it keeps running your donuts are shot and will cause a low end bog that you are talking about just a thought.
