FEATURES

Designed as an emissions control modification, the Triumph air injection system pumps air into the engine to force more fuel to burn inside the cylinder. While that may sound commendable, it comes at a cost. The downside of the system is that it creates a lean fueling condition that spikes exhaust temperature -- that encourages your header pipes to turn blue and makes low-speed throttle adjustments finicky at best.

This upgrade has all the components needed to replace the air injection system for a finished look and a cooler running engine. The British Customs Air Injection block-off bolts are machined from aluminum in a low profile design and coated black to match the head perfectly or left raw: either way they virtually disappear.

Features:
  • Reduction in Exhaust temperature
  • Discourage blue pipes
  • Reduces lean conditions

Kit Includes:
  • Low profile air injection plugs
  • Copper crush gaskets
  • Rubber nipples
  • Air box plug (for stock air box)

Nice and easy
I installed this kit and it went quite well except the instructions seem to be for the old carb models. You take out the air injection plumbing and put in the flat headed plug bolts with washers and the plug in the airbox. Viola! the vacuum caps get tossed or thrown into a drawer. Now you can get at the plugs with unbolting the tank. It also seems to be a little "fatter" off idle. Gas mileage (important to me) and power seems otherwise unaffected. I didn't polish my headers to get rid of the discoloring so I can't attest to the effect of the kit on that. BC seems to be the only kit with the flat head allen bolts. Less likely to get nicked (i got black to match the heads) during a plug change. It was the least expensive by a dollar. If you are thinking of doing it, I recommend it.

Necessary modification
Just installed the British Customs Air Injector Delete kit on the bike...
What. A. Difference! The jerkiness that the bike had at low RPM is 100% gone. It's much more confidence inspiring at low speeds, especially when turning. And it supposedly lowers the exaust temperatures as well, which is definitely a benefit. However, now it will pollute the air a little bit more. But I'll take more livability and drivability over a negligible amount of pollution any day. The first two are tied directly into my safety,

If you're slightly mechanically inclined, this is a simple job to do. If you're not, get someone to do it for you. This is absolutely necessary to improving the riding characteristics of your Bonneville, and probably to the others of the same family... though I can only speak for mine.
