I was getting ready to do the AI removal on my TBA (EFI) and Ruth's Bonny (carb). I wanted to check a couple different installation how-to's and, at Triumph Rat, they made reference to installing a resistor. My kit (Newspeedmaster.com) had no resistor. Can anybody fill in the missing pieces for me?

Plug the hole in the left front of the air box, pull the vacuum line off the intake and cap the nipple, thread the lines out of the head and plug. That's all there is to it. There is nothing electrical so I don't see what resistor you would need.
Now on an EFI bike you probably need a resistor to fool the oxygen sensor.

Removing the AI is fairly easy. The only really tricky part for me was that funky clip between the hose and the piece threaded into the head. I nicked myself on one of them, while removing it, and bled a bit all over the top of the engine.
I know nothing about a resistor (mine is carb), but Ian's most likely right on that.
After installing the bolts on the head, be sure to check them tight after the next few times you run her.
Save the vacuum hose, it makes a great alternative if you lose a "squirrel condom".
Good luck.

It's very simple, like Dog said. You should have got 2 threaded plugs w/ copper washers, a squirel condom and a plastic plug for the air box in the kit. The hardest part is removing the stems from the cylinder head, just cut the hose and use pliers to unscrew, install threaded plugs and washers. trace the rest of the junk back to the carbs and then to the air box, remove it all. Install condom and use a little silicone to install air box plug. Put the AI system in large plastic freezer bag, along with dog feces, appropriately package and mail to the EPA.  PS Use your worst enemy's return address

The resistor has someting to do with the oxygen sensor but there was not one in my "kit". I'll do the Bonny today and try to find out where my resistor went to.

There is not an O2 sensor on a carbed Bonnie, the exhaust system doesn't have O2 sensors like new EFI Bonnies. Like Dog said the phantom resistor is to lie to the EFI computer that all is well and that the AI system is still connected. PS I didn't want you to waste your sunday, I couldn't tell if you were joking or not.

So I've learned. I have also learned that the process for a 2008 carbed Bonny is different than what we have posted around here (for example, not vacuum hose/fitting to cap). Might just be a standard vs. TBA. Don't know. Here's what you do for a 2008 Bonny. http://www.triumphrat.net/twins-technical-talk/80489-2008-bonneville-air-injection-removal.htmlFile under 'learning experience'.

Thanks for that info. I've done tons of these on both TBA and standards, they have been the same. I was unaware of the 08 changes. If you have any questions you might post a question over at forums.delphiforums.com/New_Bonneville/messages. Jenks of Jenks Bolts started the forum. Now that you own a standard it wouldn't be a bad idea to join. Good luck. http://forums.delphiforums.com/New_Bonneville/start

Good idea, I'll check it out. The process is basically the same but there is a convoluted plastic contraption between the airbox and the reed valves and no vacuum line at the carbs to deal with. No harder, just different.

The resistor is to fool the computer if you remove the air pump of the AI - not the O2 sensors. The O2 sensors can be left in but turned off at the computer using TuneECU (free) or Tuneboy.
It's not a good idea to remove the AI and NOT turn off the O2 sensors.
You can leave the air pump on - you just disconnect the hoses to and from it. It will still operate and produce an annoying clicking noise but is otherwise harmless. As stated - removing the air pump requires the resistor to fool the computer. I can't remember the resistance required and I can't easily check (at work). A search of the Rat forum should produce the resistance - that's where I found it.
Cheers, Richard

Yeah, the Rat forum is where I found my other info. I haven't done the EFI bike yet as I wanted to get as much info, such as yours, as I can. Your post is the first one I believe I've seen referencing turning off the O2 sensors. I used to do all my own wrenching but, when I was raising my kids, I farmed it out. Now I'm back in the saddle but there's this dadgummed EFI and on board computers to learn about. I was under the impression that the O2 sensors worked in conjunction with the EFI. Not so? If I understand what you are saying, I do NOT need the resistor if I leave the air pump in place and just neuter it. Correct?

Smokey3214,
I have done the entire AI removal on my 2010 Speedy, including the resistor and disabling the O2 sensors via Tune ECU- pretty straight forward (even for a not mech type like me).
I have a standing offer to loan out my Tune ECU as long as it is returned in reasonable fashion, as well as a spare resistor (they came as a two pack) that I will throw in the box if you need it.
Just send a PM if want it.
Cheers,
Drew

Thanks Senior Chief. As a former Navy 'zero', CPOs saved my a$$ and my reputation, such as it was, on more occasions than I can begin to recount. Of course, the same is true of any officer worth a damn. It's only natural that a Chief would answer the call again. I'll PM you and set it up. I want to bone up on TuneECU first so I can make the turnaround as quick as I can. Thanks, again,
Chet

Same as me. Computer tuning is easier than it sounds. A bit of reading and you're up to speed.

Yes they do. They monitor the mixture in the headers (in closed throttle position only) and the computer turns on the AI when the exhaust mix is too rich for the atmosphere greenies. If they are not turned off when the AI is disabled then the computer is trying to fix a mix but nothing changes (because the AI is disconnected) and so it keeps trying.

Correct. You'll just get annoying clicks as the AI air pump turns on and off. But it's harmless. The resistor to replace the air pump is an easy mod.
Cheers, Richard
