Hey guys,

I have been riding for a couple of months with my new 400 and every time I turn off my bike I get a high pitches squeak coming from the fuel tank.

My girlfriend also rides the same bike and we took hers off for a custom paint job and it was still squeaking while it was disconnected. Is this a pressure adjustment in the tank or something else?


Cheers guys.

Nothing personal but you can probably hear a collective yawn from the forum regulars regarding this post.
It's the fuel tank vent squealing, they do that so it seems.
There's a whole thread dedicated to this issue on here somewhere.

The more fuel in the tank the more it happens. Its pressure being released.

Probably worse on a hot day esp if parked in direct sun I'd imagine.
I don't really know for sure as it's too cold where I live Lol.

I know the CBR300 spits fuel out the tank breather hose on a hot day.

Uhmm.. Scuse me, But this is the first Iv'e heard of a so called tank squeak. But it makes sense, The Gas-Mice get hot and start squeaking cause they want out :grin:

I'll trade you until it cools off here. It was around 108 F today and got up to 114 F last week.

No, in reponse to dealer feed back Kawasaki have dropped the tank mice on the N400. Apparently they had too many warranty issues with fuel pumps clogged due to mice $hit.

Hmm, I live in a hot, humid tropical country but I've never heard the squeak. Maybe I should be more attentive

If you park in the shade this likely won't happen.! When its hot enough out and your bikes sitting in direct Sun light, Vapor pressure inside your tank builds up and it will start whistling at you.

So wait are you saying I shouldn't do the aftermarket fuel tank mice upgrade?!!

Yes but make sure they are white ones, they seem to perform best. :wink:

Originally my 400 came with the mice mod - Free. I read on a forum that mice mod shavings were clogging up the fuel filter, So I Paid a little extra to have it removed. Proof you can't believe everything you read.
