Ok.. What's the deal with this grey wire everyone is talking about on the WR? And what's the advantage to removing it?

The grey wire is an emissions circuit, by eliminating it, you change the timing of the spark to create more snap, and a few more fumes. TRY IT!! You'll like it!
its under the tank, strapped to the frame. :)

Does it require any jetting changes?

Mine didn't. It did perk up the mid range a bit though.

I noticed that you don't live too far from me. If you like, drag your bike over and we'll pull your wire and install YZF throttle stop. You will be amazed :) and thats only the tip of the iceberg. There is a small area by my house you can try mods out.

The Grey wire resides in the only 2 Wire connector in the wire bundle under the right side of the tank. Cut it, seal it, ROOST IT!
