Brief Description: Drill 1/4" Anti-Rotation Hole in Fork
I used a drill jig to make sure the anti-rotation hole was straight and 90 degrees or perpendicular to the left face of the fork. I step up the drill sizes and finished things up with a 1/4" reamer. My only concern is how close this new hole is to the large lightening hole just ahead it. This really shouldn't be a problem since there is plenty of edge distance and both holes are on the centerline of the fork.
