Well, if you haven't changed the tube... that's sure a good place to start on finding that missing power...

Disconnect the air box from the boot and pull out that plastic part of the tube.
Have a good look inside and you will see why.
You might be able to get 3 fingers in that thing vertically... if you have small fingers.

You really have to take it off and have a look at it for yourself to appreciate the problem.

Thanx I will check that this weekend. Can that piece be taken out? What would be a better bet? Fuel ATV Intake or the Fuel Customs Intake?

Fuel Customs has a bit of an edge on the Fuel ATV setup.

I'd go FCI between those two.

LOL... depends on where you ride....

I prefer the suspension first, but didn't do it first on the KFX either.

After you get those things on and get dialed in, you are going to want to do suspension for sure. I can get mine really really out of shape now... It's going to be really important in getting that extra power to the ground and making more use of it.

I see what you mean. I think I want to get the filter with the airbox. I do some trail riding and there is an occasional Mud puddle in my way.Or is going with out the airbox better? Now that I ordered the Procom, did you say that I should keep the TFI controller on or remove it and keep it for a backup?

Just ordered my Fuel Customs Intake. Got an awesome deal on Ebay. I can feel the speed that this thing will do.
