Odd whistling noise after parking

[omcrider]

OK tried to search this and system pulled up nothing. I have noticed a whistling sound after riding and parking bike in garage. It is very slight noise like air being released through a small opening. Similar to stretching or pinching the neck of a balloon as it releases air. Can't remember hearing it before but had valves done recently, could a air hose be pinched or is this a typical cool down noise others experience. Again very slight hard to hear but audible in a quiet environment.

The fuel tank venting. The noise is coming from the cap, where the vent is.

Perfectly normal and nothing to worry about.

I get the same thing, vapor pressure bleeding out of fuel tank.  Push on the fuel cap it will change or open the cap and hear a whoosh.

Cool thanks, never thought much of it then I got that quick upper left red light flash and the FI or F1 pop up on screen then it was gone just as quick so wanted to reassure myself that I didn't have a pinched line somewhere causing a problem.

I've got a pinched nerve or two, but no pinched lines.

I have been known to pinch a nerve or two myself.

Had to pinch a loaf this morning, but I didn't hear a whistle, only a wooooosh...
