Ah! two tanks.. That explains a lot.
Can you state which tank fits a carburated Monster and which fits an injected Monster as the fittings, including the filler cap are specific to each variant and cannot be easily interchanged. They also differ in the clearance beneath the tank for the different airbox/battery layout. The fitting of the seat to the tank is also different between early and late models and will have an influence in which Monsters, or rather which seats will fit.
