I dont know how it would effect a 2012 (EFI) bike but on a carb bike its the main can and two small solenoids plus all the vac tubing.

I removed it from Karens bike (07 America - Carb) and it was easy. I did have to cap the vac ports on the carbs though. Aside from that its fairly straightforward. Remove one item at a time.
