Bonneville America Forums Forums Technical Forums General Tech A.I. removal question

When I remove the A.I., will it require rejetting the carbs? Based on how the A.I. works, it doesn't seem like it would affect the fuel/air mix BUT, shizzt happens and I want to do things right the first time.

No rejetting required. The AI injects air post post combustion and is essentially a stand alone, passive means to minimize hydrocarbon related emmissions.

Only thing you'll want to do after removing the AI is adjust the idle mixture, which is often set poorly at the factory and also contributes to popping and blueing. Otherwise the bike'll run exactly the same with or without the AI.

You will need to balance\sync your carbs as well

A quick question, re AI. Am I right in thinking that the pipe that enters the airbox behind the LH side cheese-grater is the AI pipe? And if I block this off, it'll disable the AI? (I'm thinking of just putting some tape over the end and then pushing it back into the hole in the airbox-will this work?) The reason I'm not removing it completely is that my local stealer isn't very flexible when it comes to the warranty (which I'd like to keep) and I'm not tooo fussed about it being there, as long as it aint messin' up my pipes!!!

It's been awhile since I removed one but I believe there is a vaccume line to remove and plug as well.

Hi Neill.

I took a jiffy marker cap with me when I went to pick up my new bike from the dealer last year. I shoved it into the large hose from the air box side before I drove the bike home (220k). Make sure you put the line back into the air box.

I had that in there for quite a while before I finally had time to take the AI stuff off. I don't see any reason why you couldn't leave that line plugged up all the time.

More to it than that. The tubes that enter the head just to the outside of the spark plugs are the AI. They have to be removed and the holes in the head plugged. The valve? that they hook into as well as the vacuum tubing and the tube to the airbox have to be removed to do the job right.

sells an excellent kit with full instructions.
It shouldn't affect your warranty, and no other mods are required as all it does is puts fresh air into the exhaust to help burn any unburned fuel.
You will however want to do at least the above mention maintenance items anyway, and I'm sure that you will then want to change pipes, modify your airbox, etc. which will require rejetting

Bill , he wanted to leave the parts in the head. Not knowing the internal working of that thing myself. Do you think he can do that? What I posted was that in addition to the tube at the air box I thought he had to at least disconnect and plug the vacume line.

I would advise against leaving them in if you want to disable the system.

Perhaps I should clarify: as a short-term fix, will blocking off the end of the pipe that exits the LH-side of the airbox disable the AI or cause problems? I realise you can get kits to remove it but, for now, I want to leave it in but disable it. Thanks, neill

Mechano said he installed a valve in that line to turn it on and off. I never tried it and I am with bigbill on this one. I think remove or don't remove but don't go half way.

What Dog said.

But,
If you want to, I think you would have to disconnect and plug the vacuum line at the valve.
It's under the tank, and pretty easy to identify once the tank is off.

The hose to the airbox could be left as is.
