Who blocked their AIS? Do you have oil coming out of yours?

How did you do it, i opened up my airbox, saw the little hole and placed a bolt in there and started the engine...saw no difference in popping and backfiring so decided that i might not be blocking it properly.

Will some silicone do it?

Why is their an oily residue around it?

Are you very sure you have the AIS pipe as it should be bone dry no oil at all???????

Sounds to me you have the engine breather pipe.

The pipe is on the outside of the air box on the left side of the bike it is the top hose.

The hose is to be removed & blocked on the out side of your air box, using a plug. I used a bolt & ground the head round & inserted it into the pipe, that way there is no chance that it will be sucked into the motor & distroy it.

This subject has been discussed in lenght in the ASK KEV supporters forum, blocking off your AIS pipe on your XTX & XTR will reduce the popping back in the exhaust system, on the later ECU's the popping is reduced by 98%, it also stops that annoying noise from the air box at around 3000rpm when you are on the cruise or just opening the throttle.

Quote from the ASK KEV section

If you want to get rid of the poping back from the exhausts, you need to block the AIS pipe at the air box end. This will reduce the poping back by 98% on 07 to present XT's & by 50% on 04 to 06 models. I use a bolt & ground the head round & left a small bit of the shaft so you can get it out of the pipe easily. You then refit the pipe back onto the airbox, otherwise it will suck dirt into the motor.

Hello!

I read everything related to this issue of annulment of AIS and I have a question that is:

* Aborting the AIS, the CO is in the same value found at the time of the cancellation, or CO can re-register, or cancel will obey after the insulation?

Other:

* This complements the AIS and the CO or each system functions independently, if I touch one harms the other or not?

I ask this because the 2 deal with exhaust gases, in my opinion, something will complement ......

Opninones welcome and in this way we learn and improve all .-



My compliments .-

AIS stands for Air Intake System, AIS injects air after the exhaust valve & has no effect on the running of the motor, it is an emission control device that burns off the hydrocarbons after the exhaust valve.

Co adjustment through the dash does effect A/F ratio & the running of the motor but only up to a TPS angle of 18, after a throttle angle of (18 TPS) the motor runs on a 3D fuel map & the Co adjustment does not effect the A/F ratio.

Hi Kev,

I am new to the forum and the XT world. I just bought a XT660Z ABS (2014) and realized that the machine has some serious popping from the exhaust. Would your MOD featured above also work for the XTZs? Is there anything specific that I would have to care for?

Cheers
Prit.
