Excuse me guys, I have a really silly dumbass question here:

I bought AGR blanket kit from OTR earlier on as I didnt like all the popping and banging when closing the throtyle but just had it mounted recently. Had it done at a garage together with some other work as I am not much of a mechanic myself.

When I the bike back the garage guy told med that they had to remove a part to fit the "popstopper" - please look at the attached photo. What is this and what is it good for/what does it do?

By the way - the bike seem to pull a little better at low revs after this removal... :-)

It is just part of the AGR plumbing. You don't need it any more since the blanking plate has made it redundant. Other people would have jammed something into the rubber tube to achieve the same result.

Otr supply the kit with two sets of bolts. Short so you can remove all the AIS bits and long so you can slip the blanking plate in and keep everything looking stock but still be blanked off. So the didn't have to remove those parts but I guess they chose to.
I would be checking to make sure they have also blanked the air feed to the solenoid from the air box as I removed the lot when I did mine.

This is pretty important. The pipe that connected to the part in your photo on the AIS valve must be blocked. This can be done at either the air box end or the valve end.

The valve will still open and close, just as it did before. If it has not been blocked then unfiltered are will get sucked into the "clean" side of the air box when the valve opens. Ideally this part should have been left in place (and the rest of the AIS, or removed completely. Your setup seems to be neither one not the other?

Oh s**t.... :-(

I have no idea of what the garage have done. I have ridden the bike a tour of around 100 km. The popping has gone almost completely and the bike even seem to pull a little better on low revs. Could that be a sign that the garage have blocked the AIS valve in one way or another? How can I check if it is blocked or not?
Can this setup damage the engine in any way?

Thanks all for answers by the way!

Here's the diagram of the AIS system:



The parts circled red have been removed from your bike. The parts marked yellow are still fitted to your bike.

The AIS valve (1) will be open to the atmosphere at A, which is where the removed parts were once attached. When the valve opens this will allow unfiltered air to be drawn in to the airbox from this opening.

You will need to block the hole at A, or block the airbox end at point B so the airbox has no unfiltered connection to the atmosphere. Alternatively you can refit the parts in the red circle but use the blanking plate under the flange when fitting to the cylinder head. The final option is to remove everything (as Matt suggested) and block the hole (B) left behind in the airbox.

Don't panic though! You won't have sucked in much unfiltered air in 100Km, as for a lot of the time the AIS valve would have been shut anyway. It would be more of a problem long term.

Hope this helps explain things a bit better?

Nah - its not a part of the AGR blanket kit. Its a part who was on the bike and was removed to fit the blanket kit.

I just wonder what it is and what use it had?
