"Radiator" shrouds bolt to the tank, and then mount on outriggers coming from the frame near the headstem, which can possibly be seen in the pic showing the carby and space under the tank. Tank is mounted via a single bolt below the headstem/bars, and two bolts at the rear of the tank under the seat, as well as the usual "tongue" going under the headstem.. The way this one all fits together is much better thought out than the blitz... if they wanted to, they could have made this tank about 3-4 litres bigger... there is a lot of unused space under there...
