Hi Mort, do you mean block the pipe and then reconnect it?

Yes mate:homework:

Hi Kev,

I'm an old hot rodder from the 70s. Air Injection started about then. It's actually not so innocent with regards to the motor. Burning the leftover HC in there generates a lot of heat. When building a V8 for power, we would always remove the AI because otherwise the exhaust manifolds and even the cylinder head exhaust ports would get too hot. I remember seeing manifolds actually cracked from the AI heat.

So in fact, the mod you suggest here should be GOOD for the cylinder head and header pipes. Less excessive heat is a good thing.

FYI and pleased ta meat ya!

AIS Bung
 

If anyone has removed the hose from their air-box then blocked the hole with a bung, what diameter did you use? My bike's not at home for me to check =P

Cheers!

AIS Plug
 

After a few months of riding with the AIS plugged I found that the mod didn't reduce, or increase the amount my '04 XTX crackled & popped.

I've reconnected the AIS after removing the bolt I had snugly blocking the pipe and haven't noticed any change in the frequency that the bike pops, although it seems more prone to doing so on a warm day.

The bike has a MM/Scorpion 2-1 pipe fitted, DNA Stage 1 & 2 Filter kit and a PC3 with a custom map.

All it dose is sucks air in from the filter box on closed throttle.Give it more fuel that will help.:hcrap:

-Did it today...Popping is gonne...!!! :smilies0349:

UPDATE:
-Popping and backfiring... pretty much there... as always...

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.

Pls help
 

I have the XT660z and I cant seem to find the pipe?
I can see the black pipe in the above pic below the red arrow?
Pls help
