Bonneville America Forums Forums Technical Forums Performance Mods air injection removable kit.?????

Hey Folks
I know when I joined this site I saw a kit for removing the air injection but now I cant find it. Any help with a link would be appreciated
Thanks Tim

Check the Tech Vault under "How To's".
Very Cheap Fix!

You don't need the kit, unless you really want to yank everything out. You can just disable the AI. Not 100% sure of the procedure but there was a post about it. You have to reverse the tubes on the Reed valves and do a few other minor things. Everything stays in place so no one knows it has been disabled.

You got 2 options 1. Plug up the 2 rubber tubes at the top of the AI pipes with suitably sized ball bearings
2. Take off the whole unit - all you need is 2 x Nissan Bluebird sump plugs ( 12mm x 1.25 ) + 1 x 19 rubber plug for the airbox + 1 x rubber cap to close off the Vacumn port on the LH side intake manifold.Take off your Tank first & the rest is self explanitory. No 2. option is better because you can access your spark plugs a lot easier
Hoffo

I bought mine from newspeedmaster.com, it is very easy to do and the instructions are very good, this mod is a must.

Ditto on the sparkplgs being easier. I think Hoffo hit it right on. Mechano would be the name you can search for the cheap method. He said something about the ball bearing he also mentioned using a ball valve so you could turn it back on if you needed.

Thanks thats the one I was looking for.

I've just disabled mine (I think)
Remove the tube going from the carb manifold to the pump. Cut two 1" sections from it. Twist a screw/bolt into 1 end of each. Attach these short pieces to the nipples on the carb manifolds, one on each side. In doing so, you remove a dust cap from the LH nipple; just slide this over the nipple on the pump that you pulled the tube from initially.
I've got some sump plugs for a Suzuki SV650 to plug the tubes going into the head...I'll do this when I can be arsed removing the tank!! (Any 12M bolt with a 1.25 twist should do-just cut it down to suit.)

I just removed the AI from my TBA. I bought the removal kit from Brent at New Speedmaster. The kit was simple to install and the instructions were easy to follow.

I've just come back from a quick run and the popping in the exhaust is almost gone. It could be my imagination but I think it sounds a bit better too.

Anyway I just wanted to thank Brent for the removal kit. (I also bought the universal mirror adapters but that is a another story that will play out at Xmas time when I spoil myself with new mirrors )

I disabled my AI. Pull out the hose from the AI to the airbox, fold it over and zip-tie the fold in place. Cover the hole in the airbox with black duct tape. Added bonus, if you get a backfire, the duct tape will pop off the hole and prevent the dreaded Air Box Ka-Blooey!

Just curious, why would someone want to remove the AI system?

The AI also helps make the pipes blue faster and I believe robs some performance.

If the air injection is so bad why did Triumph design the bikes with it?

EPA regulations

I think it does rob some performance , carb balance can't be great with that thing robbing vacume from one side.

That would be correct if you broke out the microHP meter! The vacuum needed to operate the AI valves is insignificant. No one would ever notice any performance difference, either seat of the pants or measured on a dyno.

i like that throaty pop!

A thought just occured to me (it happens): if the idea of the AI is to burn unburnt fuel, why not burn it in the cylinder and maybe gain a bit more power from it? The hole's there, why not throw another sparkplug in that sparks just after the current spark?

this hole is not ending in cylinder !!!!!

I was recently corrected on that one. The AI hole in the head goes in after the exhaust valve.

Does AI removal require any additional tuning or carb adjustment?

Not really but don't forget to disconnect the battery.
