Why ?
Geoff at Hilltop says there is no benefit and the stock filter is very good

Less money in your wallet
Zero improvements
You'll have to clean and oil it more often
The original paper filters do actually filter more -> less crap going through
[full disclosure: I have K&N on some of the bikes]
Lovely induction sound. Makes it all worth while.

Wouldnt bother. I have one, put it in and noticed no difference. Used it for a bit then put stock back in and again noticed no difference.
It's sitting in its box in my garage, just not got round to selling it yet. Use a K&N in my transit and individual filters on my GSXR1100. Main reason on Transit is its fit n forget on a not to particularly advanced engine and the GSXR for tuning.
Did once find a filtration comparison between a group of filters and the K&N's didn't come out to well. If I can find it again I'll post the link.

All the reasons right there.
And it's very easy to over oil it, then it will flow a lot less air than a standard filter.

Only reason you might want to swap to one would be if you knew you were going to a lot of water crossings.
The standard paper one might not last too long when soaked in water.
I asked the mechanic who services my GS and he advised against it too but gave water crossing as a reason for doing it if you really had to.
No other benefits to be gained from giving K&N your money.

You get a nice sticker in the box!!

For water crossing a paper element filter will not let as much water through as a K&N so will hopefully clog up and starve the engine of air.
A K&N stands more chance of allowing enough water through to hydraulic the engine.
K&N do not filter nearly as well as a stock paper filter. Have a look in an airbox that has had one fitted !!.

David Vizard did some testing on K&N filters way back. He found they filtered extremely and flowed a lot better than paper elements.
However if dyno testing shows the GS K&N is no better over paper there really is no point. If you need better air flow chop the intake pipe and flat the end. It's got a smaller intake area than either throttle body so has to be a large restriction.
Post the results in the "my bike is too loud" section.
