OK; just to clarify, the small hole in the airbox (upper right of picture) is the one that needs something shoving down it to block it off to stop the popping?
If I wanted to go further and remove the whole AIS system, I should get a blanking plate (eg. of the kind sold by offtheroad), which fixes on the engine end and plug the hole in the airbox; so then all the AIS gubbins in-between could be removed? Or have I got that horribly wrong?
Thanks.

Yep, that's the hole. However, you'd be best to remove the hose from the outside of the airbox and block that securely. If you shove something the hole inside the airbox it's going to be more difficult to secure and if it does come loose there's a small chance it could find its way into the throttle body/motor.

No, you've got that horribly right! ;)

Genius !! although i might just go with a stealthy old school petrol tap look :-)

first ride today with the ais blocked and it seems smoother as well.

I like scaring people with the pops...


I want to get rid of the airbox sooooo I am going to put in a silicone intake pipe to a pod and position it inside the front wall of the airbox (front wall and battery box may stay) sharpen up the Dremel. Also the ais will be tapped so I can turn the popping on/off with a T just behind so that the crankcase breather sits just on the air filter (new 14mm) side of the tap.

And all this has to happen prior to my dyno tune on the 4th !!!! Pc3 tune. Grrrrrr !!!!

Result will be a cleaner looking airbox free bike. Tasty !!!

Do you need to take off the tank to get to the AIS pipe in order to block it? It looks very tight in there, especially with my chubby hands.
Cheers.

No, there's no need to move the tank.
If you wish to block the hole in the Airbox you can remove the R side of the Airbox and easily access the the hole.
Or you can remove the hose from the outside, held on by spring clip thing, poke the head of a 10mm allen headed bolt in, and place the threaded portion of the bolt in the Airbox hole from the outside, and replace the hose.
Long nose pliers and a torch all that's needed:occasion14:

Excellent! Thanks.

OK, finally had a chance to block the AIS pipe today. I can't actually see the prongs on the clip as they are facing in towards the bike rather than out towards me; so I can't get the long nose pliers in to undo the clip. Am I missing something obvious here? I really don't want to take off the tank if I can avoid it. Any advice? Don't worry about stating the obvious as I am really stuck at this point.
Cheers.

A Hoffmann type laboratory clamp is ideal for blocking the AIS pipe.

Can be fitted/removed in seconds without removing the pipe. Will not damage the pipe as they are designed for this exact purpose.

I first thought of using one as a temporary fix to shut of the AIS when on the dyno. Got mine from work, but they're only a couple of quid. Make sure you get one though that has a gate so it can be fitted over a connected pipe (some types are closed and need to be slid over the end of the pipe).

If you know/have a child at high school (or a teacher) they may be able to procure a "free" one for you... ;)

As always: thanks Peiades!

FYI - Here's a photo of the actual Hoffmann clamp I use fitted to the AIS pipe...
