not sure about the differences between US and UK, The AIS is mounted on the right side of the bike,it will be blocking your view of the carb it has some pipes going to the block.
It is not essential to remove. It is supposedly to reduce emissions, all it does is adds air directly into the exhaust to help burn unburnt gases, basically it makes annoying popping sounds a bit like the old Brit singles. The Grey wire is a ground or earth to you, most people unclip it then silicon over the connector, it bypasses the WR ignition mapping and goes to the YZ, gives more hit in the middle and upper. Your best bet is to do a search as these subjects have been covered extensively. Also read the post at the top on free mods.

If your jetting is OK to start with, then no cutting the grey wire will not affect your jetting.
