Usually, this problem is indicative of a vacuum issue with the motor. Either a leak somewhere or poor synchronization. Given that the bike is fairly new, and it's somewhat intermittent, I'd start by verifying that all the throttle bodies are properly synced up and try to eliminate that as a possible problem. If you think they're synced from the factory, you're WRONG! And it's recommended to do this once every 12 months.
You can also verify that your throttle cables are properly slacked and not binding. While the motor is idling, sit on the bike and move the handlebars full lock in both directions while listening and watching the tach. If the engine RPMs go up or down while you're doing this, the cables need to be adjusted. And use your hands on the end weights of the bars to prevent your hand from turning the throttle while you're doing this test.
I may not be perfect, but at least I don't ride a Suzuki.
