shut down noise 09 rtx

[faithfullyamaha]

Recently went through my air box and everything to prep for season. The sled is running great however when I shut down the sled there is a noise that will persist three or four seconds after shut down. It almost had the same sound as a leaky tire. I was thinking vacuum leak except for other than the sound the sled runs perfect.

any codes pop up?
check oil line breather and 2 vac lines on top of airbox maybe.

no codes no check engine light those lines have been checked multiple times. I'll be able to post a video tmrw with the sound

I'd be curious. do you kinda know where the sound is coming? front under tank out back?

just a thought, might be from the snow on heat exchanger underneath melting??

I wouldn't think it would be any evaporation off of the heat exchanger I haven't ran it long enough to do anything like that. There's minimal snow here as of right now. Sounds like a noise from the engine compartment. I'm going to double check the return line on the gas tank though

Coincidentally, there is a thread over in the RS section about a "hissing sound" when shutting the sled down. One of the Nytro guys said it is a, "symptom of a dry sump oiling system." Does the Phazer have a dry sump oiling system as well?

yeah it does

yeah it does

so it's normal or it needs to have a new oil pump put in?

Are you sure its not just the fan on the radiator spinning down? When I went from the 07 Phazer without the fan it caught me off guard when I heard that fan on the 09. Just a thought...

I'm half deaf, so I have never heard the noise on my Phazer, but the other thread indicated that it was normal.

the noise just stopped. we got a decent amount of snow here and when I stopped to gas up I shut down the sled and the noise was gone.
its kindof a relief but I still would have liked to know what caused it.
