The fan on my Frenzy doesn't seem to sit on the crank well on my YS50ST. It's causing the fan to rub on the shroud? I tried to torque the crank nut pretty good using the crank holding tool.

How did you fix this issue?

Some people leave out the thrust washer between the fan hub and motor, but this leaves a small about of clutch sticking out of the bell. Or they shim the bell down a bit to compensate.
I had the same problem since I am running the Redline 53.
What I did was left it as is and remove the fan shroud from the frame and take my dremel to the frame with a small sanding disk. I raised the curve on the frame about a 1/16 of an inch. Then I elongated the 2 screw holes in the frame a bit.
Put it all back together and bolt the motor up. Then just push the fan shroud up a bit and tighten down the screws.
Took all of 10 minutes, my clutch is fully seated in the bell, and with the thrust washer in place I have no worrys about the crank rubbing the backing plate on the motor.
