your thinking the engine is twisted in the frame? , if that's the case the rear wheel can be adjusted to compensate, doesn't the rear wheel have draw bolts on each side?. a 1/16 shim seems a bit extreme, you only want to go the very minimum to line it up, don't look for perfection, even .5 to 1mm shim would most likely get it close enough to stop the side load on the bearing, and cocking the wheel very slightly, won't affect handling. just remember to try small adjustments, if you go to far it can and will cause problems. if you can lay a straight edge across both pulleys to confirm how much misalignment exists using your eyes on something like that can be very misleading
