For awhile now I've noticed when I shut the bike off (I hit the killswitch) sometimes the bike will, right before its completely off and silent, start to make a gurgling sound for anywhere from like 1 to 3 seconds and then shut off. I have no idea what it is or if its a bad thing, but it is annoying/embarrassing.

 

maybe it has gas

 

lol, well it sounds more like its drowning

 

like a glug glug sound?

 

not really, more like a gurgling, like if you were to take mouthwash and gurgle it. Its about the same gurgling speed too. It lasts about 1-4 seconds and usually starts louder than it ends.

 

my 99 Sportster used to do that sometimes. Never did figure out why

 

Could there be something leaking and you're hearing the last of it burning up on a pipe just after you shut it down?

 

Is your bike fuel injected? 07 or later I think. If it is, what you are hearing could be the fuel injection system depressurizing.

 

Nah, its not a leak. It sounds like its coming from the engine, and you can feel the bike do it.

02, carbed.

 

My bike does that occasionally. Always has. I can't determine any common denominator for the occurance. It's obviously not a major problem. I have over 55,000 miles on it now. It is a bit embarassing at times. If the bike happens to do that with people around, the way that I deal with it is just to say, "Oh, just shut up bitch". Works everytime.
