Petrol tap (left)
Left-side petrol tap for the fuel tank, controls fuel flow to the carburetor.
This is the left-side petrol tap for the fuel tank, the fitting that controls flow from the tank down to the carburetor. The catalog lists it as the main tap on the left, with an alias number of 82-4971T and the older letter-prefix form F4971 turning up in earlier parts books for the same physical part.

It shows up in the parts-book listings under the PETROL TANK, TWINSEAT AND CONTROLS figure, which is where you'd expect a tap to live alongside the tank fittings and control cables. Our records tie this part number to catalog appearances from 1969 into 1970.
The factory later renumbered this to 82-4971T, so if you're working from an older parts book and see 82-4971 or F4971, that's the same tap. Worth checking your existing thread and fitting before ordering, since tank bosses vary and not every tap drops straight in.
