Engine whistle

Adamastor · 07-31-2009, 05:57 AM

Hi there!

When I am revving my GN250 (equal to GZ250) engine, I hear a whistle sound (different sound according to revs). Never paid too much attention to it, but I wonder if this could be any air leak that might do something wrong to the engine... or could it be any chain inside the engine?
Is there any chain tensioner maintenance to be done? Are there any tutorials on the web?

Regards,

Sergio
