After shutting down my 2011 RT-S I hear a high pitched hum for some time after everything is off. Is this normal?

That's a normal sound for a 2011. It's got something to do with the throttle bodies being closed... You've got nothing to worry about.

Bob, I have read of other's hearing this noise after shutdown. I do not for whatever reason. My fans run a few seconds (91 here today) and then all is quite. Just wondering.B]

 

[Bob Denman]

Hiya BR! Well... there's only two possibilities... either you need to dig the wax out of your ears, or replace the batteries in your hearing aids...

I'm sorry... bad joke but I couldn't resist!

Bob, I will take your advice on my ears and hearing aid batteries...but maybe I don't hear any Spyder noise as I park next to a sawmill...

 

[Bob Denman]

I know that I don't hear much extra stuff anymore because my "selective hearing" is getting wider...

Lamonster was talking about this high pitched sound maybe a week ago... He gave a pretty good explanation of what is supposed to be going on and why...

high pitch sound

My dealer tech guy says its the throttle bodies activated in Hot start mode. The high pitch noise is present for about 40 minutes then shuts off

I agree!

The 2010 models could have a hard time restarting with a hot engine. The wine you hear is the soleniod holding the throttle bodies closed. I heard this on all 2011 Spyders at Spyderfest a few weeks ago.

High Pitched noise

Jeff and all! The Spyder RT looks and drives like a space ship. Why not sound off like one occasionally

 

[Bob Denman]

That is indeed a very good point!

hard to start

That is what I am having trouble with, when it get hot it hard to start, but it will start. Do you know what Can am is doing about this and do you know if it will get worst?
