No, that is the neutral switch. There should also be a sky blue wire, if you trace it up the wiring harness and disconnect the plug you have completed the "blue wire mod" which according to legend increases voltage allowing for easier starting. If you unwrap the harness at the switch you should find that those wires aren't connected to anything, if they are, disregard everything i've said :thumbsup:

Hey Satch, did you notice any difference in starting with that sensor removed? I broke mine trying to remove it and was going to make a block-off plate to replace it, but I was told to keep it because it assists with starting, somehow. Thats a pretty cool sight glass, think Ill have to get one.

Read this :

Blue wire mod

Does not make the bike harder to start if that is your question.
