08 Flapper mod
Here is a write up. I'm not sure if the '12 has them tho. Sounds like you have a good idea to start.
12 has a flapper and it works the same way as the write up for the 08 says, i did block off plates while i was in there and a k&n at the same time.
Buy 87 Octane.... Spend the money you save on Ohlins!
