Do yourself a favor and make sure the fork can travel all the way back (toward the rear of the vehicle) and check if the bearing is contacting the clutch pressure plate fingers. If it is, you need a shorter bearing. If there's too much gap, you may need a longer bearing. Finding the right amount of "throw" on the fork is what i had trouble with. With the short bearing, The fork movement stopped before the clutch was fully disengaged. With a long bearing, it never was able to disengage.
I ended up shifting the fork pivot point to get things to travel correctly. I suspect the AA kit requires a centerforce clutch pressure plate to get the spacing right, but I didn't want to use it.
