The last photo you published indicates a Mk 3 setup
I'm afraid I wouldn't know the difference. Maybe you can determine

The primary case moves. Have you checked your primary chain? The gap may or may not be related to your handling. I'd check the isolastics, then the shocks, then the wheels (alignment and spoke tension)the top third seems to have to large a gap.
The primary chain is fine, maybe a touch slack. There is no problem with the handling at all, just a bit of vibes mainly through the left footpegThe primary case moves.

What was i saying ??? No, the primary case does not move, only the sealing disk moves. Surprised nobody called me out on that. I agree with Stephen, if the primary case doesn't move, then there's an issue with either the location of the primary case or the z-plate. The primary case is located by the cradle (via the primary case stud) and the crankcase which is connected to the frame via the front iso. A bent front frame affecting the front iso could be a cause, or it could be the z-plate out of alignment at the rear iso tab, i.e. a bent frame somewhere that's affecting that?The primary case moves.

Yes the crankcase holes do hog out but they'd have to be really bad to give the symptoms you haveWell, I jacked up the engine, to support the weight, and removed the front Iso bolt, the mounting holes in the frame were in good condition (not oval) and the iso tube did not shift, the bolt went back in with no problem. I checked the front down tubes with a straight edge, they appeared to be straight, Had a good look at the steering head, down tubes, top tube - no evidence of distortion. I will need to machine up some long rods to stick in the frame lugs for the iso's so I can measure to see if it is in spec. Do the engine mounting holes in the crankcase hog out on commandos? I dont know, so thats another thing to check.
Yes, especially if the shims on the inner primary are left off. In extreme cases the crankcase can crack around the mounting holes, as mine did -Do the engine mounting holes in the crankcase hog out on commandos? I dont know, so thats another thing to check.
