HI all

on my first decent ridout on my recently acquired zx10r, there seems to be a recurring whistling sound coming from the fuel tank when the engine is off. it lasts around 3-5 seconds, doesnt get louder, is constant. it sounds like air escaping from somewhere?

does anyone know what this is please?

thank you

gas vapor pressure builds up and the release valve in the fuel cap lets it out. totally normal.

All of the Kawasaki's do it.
My 06 zx10, my wifes 08zx6 and a friend has a 08 zx10 and another has a 08 zx14
and on a hot day they all make noise.

So don't worry about it.

Yup...they all do it. Get used to it. You can open the lid, it will stop squealing for a few minutes.

My '08 ZX-10 and my '99 ZRX 1100 both do-did- it. I finally removed the ZRX cap and disassembled it to rectify the vent whistle. I pulled two very small red rubber one way flappers out of the cap and killed the whistle. Haven't examined the ZX-10 cap as the whistling is nowhere near as obnoxious on the 10. Owned lots of bikes and brands- Kawasakis are the only ones that exhibit this trait.
