If you study your Owner's Manual, you will find out how to tilt the tank, and also how to remove the tank. These are tiresome tasks, but essential to know if you want to service your own bike in various important ways.
Air filter. There is lots of info on this site about making your own repalcement air filter for less than $10, compared to the similar item sold by dealers for about $50.
I had a serious problem a few years ago. I needed to leave my bike out in several rainstorms (I nearly typed rainstroms) and after that it would not start. I spent over $200 to learn that insects (mud dauber wasps if U need 2 know) had blocked the tube that drains liquids from near the gas tank lid, hence rain had gravitated into the tank, and found its way to the bottom of the tank and hence to the engine, in which it would not burn.
So I think you should carefully follow the directions in the manual and drain that dang tank and get the miserable circle out of it. The two goals of prevention of problems and education of the owner will be nobly served.
Heck, I will pay you $5 to do it. Just tell me how you want the money.
