Whirring sound from right side of motor

This just started. It is fairly loud around 30 mph. I can also hear it in neutral revving slightly and when downshifting.

This was my 3rd ride since changing oil. Used a wix 51358 filter. This is the only thing done recently to the bike and first time I've used a wix filter. I noticed it was a tad smaller in diameter. May not be the problem at all but this sound is somewhat disconcerting!

Other that this change, it seems to be running just fine. Any ideas?

Although you say its from the right side a whirring sound on a 900 usually means a bad stator. Theres a sticky on this forum that should give you alot of diagnostic information.

I thought about it but assumed stator on same side of the belt. It is definitely not on the same side as the belt.

Ok! I did recently get new tires so could mechanic have gotten belt too tight and it is just now starting to tell?

*********

Forgot that I said it does this sound in neutral as well.

Just has a thought. I did the marbling thing last year to reduce popping... which worked, so now I'm wondering if the wiring twisty cap I used instead of a marble... has moved or something.

Well on the right side of the bike you have the clutch, water pump and primary drive I believe.
you could dismiss the primary shaft.
If it happens also in neutral you could dismiss the clutch.
This leaves the water pump with something stuck in it...
Just my ideas.

Do you have the old air filter? Try putting it back in and see if the problem remains. I wonder if you have some sort of air leak causing the noise?

Thought about this too! It has original filter. Bike only has 9K on it. I took it off... looks nasty so I ordered one. Cannot see any type of leak. I did see a hole in bottom left of filter housing but looks like it was made like that.
