Is this normal? Do I need to work on the carb jetting? The silencer before this was a Procircuit piece and the bike ran great.

The links in the stickied jetting post are either dead or incomplete. Can someone point me in the right direction?

Thanks for the tip. I changed the jets as per the FMF website but haven't had much luck--working on other issues right now :(.
