Pig Moans Like A Cat In Heat!

So I sits in the garage sipping on a Goblet of the Red Elixir, and Inhales some Cheap Cigar Smoke, contemplating the mounting of the new rubbers. Staring down at the forged steel weapons of mass destruction, an eerie sound beckons from the Pig's general direction. I make some deductions, I've had too much Elixir, possible but a borderline miscalculation at best. Nasty cigar is giving me a buzz, nope already have a buzz. Neighbours' cat is losing it, it will when I find it. The moaning (more like a low frequency squeal) sound definitely is coming from the Pig, and at a somewhat predictable interval. I've nailed the source down to the gas tank. I think I had heard this previously but higher pitched, and defied my delusion and just ignored it. Now curiosity gets the better of me, so more Elixir and Smoke. I pop the tank cap, and it almost seemed pressurized, I wait and the noise doesn't reoccur. I washed her and speed dried her around the block today, seemed to run like her normal Pig self. What has me worried is that I have two big rides upcoming, most of it probably Solo. Anyone else with a 2008 KLR had this happen, better yet should I be concerned?

:help

Good Morning

Not a tech and have not heard your bike but I bet it is just your tank venting. Had a customer phone in complaining of a high pitch squeal. Told her to truck the bike in. Min. latter I hear the same noise from one of the Ninja 500"s in stock. It was the tank venting. Kind of like letting air out of a balloon while squeezing the end.

Thanks. You're probably right as I've heard it since I purchased the Pig, I just ignored it after awhile. This morning I couldn't hear it as the ambient air temp dropped overnight I suppose. Yesterday it sat in the beaming sun as I removed the filth from her.

:hb:for the response.

Mine has been venting for years. Fuel expands and contracts with temperature changes. best time to buy fuel is in the mid morning, reason being it has cooled in the underground tank overnight. 1 liter of of fuel warmed up is not the same volume of 1 liter of fuel that gets chilled even though they are 1 liter each. if that makes sense.

It was common practice in the old days to fill the glass container on top of the pumps that measured the fuel early so that it would expand before the first customers arrived. These days the pumps are set to be correct at 15C.

You're really dating yourself with that analogy Miquel!:) Seems now due to cutbacks in the ol' Weights and Measures Department, I can hardly find a sticker on the pump anymore that proves anyone has ever tested it in the last decade, let alone to 15C.

:Stir But thanks all the same :hb:

PS: And tonight the Pig still moaneth! Thanks Ed for the confirmation!

'course the easiest way to test it is just to open the tank cap you hear the noise. If it's gone as soon as you open it, voila.

My 08 does the very same thing. After a ride when the tank is pressurized it does a high pitch squeal every few minutes. If I pop the gas cap open I can hear air escape and then the venting is no more. It has been doing that since brand new. I asked at the dealship about it shortly after I got it and they said that was normal. Never heard it on any bike I had ridden previously.

Me old KLR squeals all the time and it's the vent pipe. Tried to jam some old wire down to make sure it wasn't clogged once, even sprayed wd40 down and it leaked straight out the hose. It's just what the pigs do. So when we riding again?

my 04 had a kind of lazy quiet snoring kind of whistle, I took the cap completely off, dissasembled it and slightly modded the little flapper thingy inside the cap and voila, no more snoring.

My bike does it too, as well as my brothers. It is just the gas cap venting, but I took me by surprise the first time it happened.

Of course it squeals ...it's a pig :D

P.S. for what it's worth so does mine ...but probably more so when fuel is fairly low (?)
