The Infamous KDX Petcock - Repair or Replace

Update on fitment. I didn't notice until I rode today but last time I changed my jetting I didn't get my carb installed straight up. The top is canted to the fuel line side so it should have more clearance once I straighten it back up this week. That said, it works perfectly.

How to repair the fuel barb on or replace the '89-'06 KDX petcock. The Yamaha petcock I used is part# 2GU-24500-02.
