My exhaust servo makes a quick screech when the bike is first turned on prior to start up. Anyone else's do this?

 

mine does a bzzzzzzt click click click then its good. i guess its the servo setting itself.

 

I belive this is a part of the normal start up of the bike. It test the exhaust servo motor before you start the bike. Mine does the same thing even with an slip on exhaust on the bike.

 

I know it is supposed to move the flapper away from a sensor as part of a self test, but I was wondering if they should sound like they need to be greased. I doubt this is normal so I will have to research either doing it myself (external problem) or letting the shop do it. I know, HIGH TEMP GREASE.
