Where is the air filter on a K1200 LT?

The air filter is under the fuel tank on the K1200LT, you will only change these during full services, the air filter recommended change is listed at every 12,000 miles but it will not need it that soon unless you live down a dusty dirt road. This is a decent size job since the tupperware on both sides and stingray must be removed to get at the fuel tank.
