is anyone else experiencing the same thing on their 09 streetglide and if so can you tell me if this is normal or if it is a problem what is the cause thanks

 

I think I recall someone haveing the compensator nut come loose??
Might try a search for that.

 

Mine does it on start-up once in a blue moon. It's the compensator bottoming out and it's supposedly normal and not a problem. Not sure why it would happen at shut-down though.
