09 RMK 700 Air/Fuel ratio

[weinkauf14]

I have an 09 RMK 700 with CPI pipes, EJK controller, and air intake. Im having problems getting enough fuel to it. Its running around 14.5 all the way through on my guage, i've been tunning and cant seem to get it down to 12.3(if thats where it should be) any suggestions??
thanks

When was your fuel filter last changed? I change mine every season now.

I thought 14.7 was perfection. I guess maybe I was told wrong. I assume you have checked your plug color to make sure your guage is accurate?

12/1 to 12.5 /1 is where you want to be on TOP end

You would be correct if it was a production vehicle.

2 stroke high strung sled motors are a different story.

As for the original poster, where is your O2 placement (location)? How old is it, brand? What is your fuel pressure? Are you running EGT's? If so, what are they reporting?

Dump more fuel on the top end and take away through the mid range. You should see 16 through the mid range and high 12 low 13 on top. It sounds bad but that's just how it works. It will run like s**** if you run it lower in the mid. Personal experience

Im not runngs any EGT's, and as for the O2 sensor it is stil the stock sensor. The air/fuel guage is taped into the right pipe, will that be throwing off my reading?

The EJK controller i have installed came with the pipes and i belive is the same as the attitude box. It only ties into the bottom end and just recieves info from the top..does this sound correct? and if so could that be an issue
