Ridiculously easy AI disabling

Ok, I've been mucking around on this forum for the better part of a year now and had my Bonnie for about 9 months. I've seen a lot about removing the Air Injection system and always figured I'd do it eventually. This weekend I finally got in a kit and set up TuneECU and did it.

Only to discover that I could have gotten the same performance results free and in about 2 minutes. Granted, this method isn't going to remove the pound or so of junk or clean up the look of your engine, but it absolutely will take care of the whole popping on deceleration thing along with accelerated pipe bluing. This follows the whole "stick a marble in the tube" concept, but most of the people who've done that imply altering the tubes between the cylinder head and the valve, which is a cramped space and has some pretty beefy connectors involved.

What you'll need:
1) A zip tie or two.
2) Something to plug an ~15mm hole or a marble/ball bearing to plug a ~10mm rubber hose.
3) The allen wrench to take off your seat.

Instructions:
1) Remove the seat.
2) Yank this tube out of your airbox.

3a) Plug the hole in the airbox with something. A rubber stopper of the appropriate size should work, or even tape over it.
3b) If you *really* want to look unaltered, you could shove a marble or ball bearing into the hose and plug it back into the airbox instead (if you do this, skip step 4).

4) Zip tie a kink in the tubing and shove it up under the gas tank. Be careful where you put it as the throttle cable/levers are in between the carbs/throttle bodies and you don't want to impede the movement there. If you think this might be a long-term solution, it'd be worthwhile to use another zip tie to secure the hose to your wiring harness or something else out of the way.

5) Put the seat back on and go for a test drive.

That's it. It's that easy. No worries about the engine light since the solenoid is still hooked up. No hardware to replace. Don't even need any tools other than maybe an allen wrench to get the seat off. If you're like most of us here, you'll probably want to eventually do a proper removal. But this method gets you the major benefits of an AI removal for the cost of two bits of junk you've probably got laying around the house and the hardest part is probably removing the seat.

Enjoy.

Good idea, beats my suggestion of stuffing marbles up the injector hoses...

Will the same procedure work on a carbed Scrambler?

Yes. The AI system is basically the same.

Another plus to this setup would be if you live somewhere that does environmental inspections (provided it's a scheduled thing, not a suprise). Right before you go in to get smogged, pull the plug, cut the ziptie, stuff the hose back in the airbox, and you're in bunnyhugger mode. As soon as you're done, it's back to being AIless.

If you don't have a zip tie and piece of duct tape somewhere in your home, you need to tear up your man card.

Can same technique be used on EFI?

EDIT-Didnt see TuneECU on there, guessing this works just fine.

Note that it isn't enough to just turn off the AI with TuneECU. This only disables the MIL light. You must, at least, block the hose as well otherwise the system still injects air into the exhaust.

Unplugging the solenoid is even worse. Once this is done the valve is open 100% of the time instead of when idling, deceleration and warming up like at present.
