Did the Y pipes look good when you replaced the donuts? Bad Y pipes could cause the sound that you are describing but I am not so sure that they would cause the sled not to idle when hot.

Have you tried turning up the idle speed adjustment? Perhaps when it is cold the ECU has it on high idle but then when it warms up it is set to low?

y pipes looked good did a full check. would bad plugs cause this

Possibly, also possibly bad gas. Couldn't hurt to try new plugs and fresh gas. Did you try turning up the idle adjustment when it is warm?

Had the same idle problem but someone on TY told me to clean the check valve on gas tank and now it idles fine

 

[Maineland]

I will try turning the idle up. whats this about a valve on gas tank more info please.

 

[dylanjen9]

there is a check valve that is bolted to tank that lets any unused gas to return to tank. If the valve is plug or not opening the gas backs up and engine will flood at idle.

thanks dylanjen9 I will check. Sled runs great just does not like to idle.
