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.

Hey guys, Did you notice a difference in removing the AIS? I did the same mod on my WR450 and it made a huge difference. I also done the Air box mods as well, the only problem i had with this was sand. I used to ride 3-400km in the deserts of oman and if i had a technical laydown the air box could and would get a lot of sand in it. This same problem also caused a mate of mine to end up having his WR engine rebuilt. I would like to get some more grunt out of the TEN and will be doing the Filter box mods and change the filter as i dont have too much of a sand issue now being back in blighty, As for the AIS how will it affect the bike when it come to emissions testing later ?

The AIS mod has no effect on performance at all, it is a emission control device that inject air after the exhaust valve into the exhaust port. This extra air is like taking a hair dryer to a fire, it is used to make sure we burn as much of the unburnt fuel NOX gasses exiting the exhaust port to be more greener.

When the AIS is not blocked off & after market cans have been fitted will cause the bike to pop & back fire. Blocking the AIS on 04 to 06 models reduces the popping by 50%, 07 to 09 models it will reduce the popping by 95%.

Also blocking the AIS reduces air box noise when the snorkel is removed & or a DNA stage 2 filter fitted.
