My MotoGuzzi V7 was very finicky about topping up. It would barely start moving after any over-filling of the tank. MotoGuzzi had a recall for this system in which they replaced a check valve. My assumption is that the replacement valve included a smaller orifice so that sucking the vapors out of the canister didn't upset fuel mapping as much as with the original item. Maybe a consideration for Morgan?
MotoGuzzi dealer gave me the option of installing the check valve on the recall or relocating the system. I went for the latter. It consisted of locating the vapor recovery bits in a shopping bag and handing it to me. No more trouble from topping up, but if I had it to do over, I'd have opted for the repair. The system is for reducing atmospheric pollution. I have no argument with that, as long as the implementation doesn't cripple the vehicle.
