Post Gas Tank Whistle

This is my first post to the forum so bare with me.

I bought my first motorcycle ('09 250r) two weeks ago and I love it. Lots of fun, great gas mileage, looks awesome. I'm only having one issue. After riding the bike for a few miles I get a very loud whistling coming from the gas cap. There's a build up of pressure in the tank to the point of when I open the cap after riding, it sounds like opening a bottle of coke. As far as I know the fuel system is stock and the gas cap is also stock. Anyone have any idea whats going on? Thanks in advance for the help.

You need to check the tank vent line to be sure it isn't blocked or pinched. This isn't normal for the tank.

Is the bike a California model?

A.T.G.A.T.T so I may ride another day.

I'm not your mom and I'm not paying for your parts, so do whatever you want with your own bike.
