Tech question - Air injection

Hi All,

I'm new here. I recently bought a new Brooklands Green Thruxton which is still to be delivered. It will be fitted with Triumph TOR exhausts.

Question:
Does anyone know what exactly the air injection system does? And better: do you advice me to have it removed by the dealer before the bike will be "set free"

Thanks!

All the best, Luc

I don't remember exactly what this does, but I do know that it is some type of smog control device and was blamed for lots of blue pipes.

I have a carbureted Thruxton, so my experience may not be exactly as yours but; removing the air-injection did make it run better. If you have TORs, it would probably be a good idea to get an airbox removal or do the airbox mod.

Also, for the air injection elimination, I don't have a lot of mechanical ability, but it was an easy job for me. Basically the "kit" is a bunch of plugs so you can get rid of a bunch of plumbing.

Search the site... There is plenty of info about the AI system.

It's basically an emissions feature that takes excess air/fuel and returns it to the system to be vaporized... A side effect is extra heat in the header pipes which will cause the chrome to blue over time.... A lot of guys remove it before that happens...

The other answer to your question is I would be surprised if any dealer would remove the AI system as it would be illegal for them to tamper with the emission system on the bike... You would likely need to do it yourself or find someone to help you out....

Hmm, I originally wanted to get my dealer to install the BC efi upgrade kit, I'll have to check if they will now...

On the subject of bluing pipes though, does anyone know if blue pipes are still able to be ceramic coated, or should they be coated before bluing?

Dealers here didn't seem to have any issue with removing the AI, or working on a bike that had the AI removed. I know that CA does have stricter emissions policies, though...

Well I must admit, I do live in CA but I don't have any first hand knowledge of a dealer not doing it but I assumed since it was emission specific it would likely be beyond what a dealer could legally do... Someone could certainly correct me on that.

all three dealers in my area have no problem removing it but honestly, if you can read instructions and have a set of tools, you can do it in about the time it takes to enjoy a beer

*however, it might affect the map you use on an efi bike? not sure.

after dec.2012 you can't even get a dealer to sell or install a aftermarket pipe,let alone do anything emissions related-power commander, air filters etc. in calif.

My pipes were blue for a year or so before I had them ceramic coated black. That was about 5 years ago and they still look good😀
