Spark arrestor installed on YZ125--bike dies after 5 minutes and won't start back up

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?

Just make sure you are viewing it with Internet Explorer, Firefox doesn't like the formatting on the page and will display a white background. IE displays it correctly.

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 :(.
