BIMOTA SB3: The Mystery of the VM33

So the other day during the carburettor check
something felt off
 

 
not that it matters, but this damn bomber is heavy
 

 
the intake manifold looks like the later style, but the shape is different… 68 mm pitch with metal reinforcement
 

 
does this carburettor even come in 33 mm?
there was a 34 mm GS with vacuum operation, but a 33 mm VM? that’s wild
is this super rare?
hmm!
overseas… Mikuni VM30 Performance Special
let me open the throttle and get a better look
