A well documented issue. There are all manner solutions out there too, ranging from bizarre DIY methods to off-the-shelf accessories. What works for you is down to personal preference, how tall you are, the kind of helmet you wear, how you ride etc. Search for "buffeting" and you'll get plenty of ideas...

I hope its not running lean and doing damage etc. Its my first fuel injected bike so have a bit to learn.

The popping is the AIS emission control doing its job (passing air into the exhaust ports just after the valves to detonate any excess fuel in the exhaust). With cans and a K&N it isn't entirely necessary to alter the fuelling, it'll be fine, the ECU will sort it out to a degree. However, bear in mind all XTs run lean with stock fuelling, and even in standard trim benefit from more fuel. Adding a Power Commander or Kev mod, together with an O2 controller/optimizer can only help and you will reap rewards in terms of smoothness, tractability and power.
