Maybe there's something in the right muffler blocking the flow causing more flow out the left side,how does it run?

How good are you at wrenching? you could take the mufflers off easy enough. Start the bike and see if the head pipes are clear. I wouldn't let it idle long with them off.

Ah Ha!!! I have found out what it is. Its the active exhaust flapper thingy us guys have in Europe. When at idle it closes one of the exhausts off. When you rev it opens the right hand side exhaust to let the gases escape more quickly. I activated it by hand and the pressure is about the same on both sides.

Talk to your dealer if you want the valve open all the time ... it's easy to fix. It was very annoying for me to hear the sound move from one side to the other when I got my Rineharts.
