Great, please PM me your fuel map to have a look at when it is done.

So the other day i set about blocking my AIS pipe, disconnected it from the airbox, the upper hose on the left hand side of the box as on the picture, and once i had got it off and was hunting for items to block it with, i felt something solid about 4 inches into the pipe and it appears that my AIS pipe is already blocked with something :/ Im pretty sure i got the right pipe, and i rang the guy who owned the bike before me and he didnt have a clue what i was talking about! IDEAS PLEASE?!

thanks
 

great tip easy to do very effective.

I blocked mine and removed the plug and it felt like I had an improvement. it was around the same time I removed my baffles and cats from the std pipes (see my budget standard pipes uncorking).

Im onto a new project xtr now and was wondering how you would go plugging the airbox and totally removing the pipes and AIS assembly altogether? I could just make up a little plate to go over the hole on the head.

surely all that rubbish wouldnt be needed if your disabling the system.

I plan on running aftermarket headers with no balance pipe and uncatted powerpipes. Ill be riding it overseas where theres no emission hassles and I can have it dynoed here before I send it.

so what do you think Kev and me mates? just remove everything and plate the hole?

No problem to block off the hole with a plate.

Please send to this post new pictures of AIS removal!!!

All this type of info is in the modification index.

5/ AIS removal stop your bike popping.

I thought the pictures will be shown how to remove the entire AIS system, not just blind pipe.
How to make a plug for the air intake AIS to the cylinder head?

I have personally never removed the whole AIS system & I have not seen anyone else document it on the forum.

If you want to remove the complete AIS you need to blank off the air box & the make a metal blanking plate for the head.

Exactly, I want to do. Just thought someone already did it.
