Hi Charlie, Just had a look at the tracings I made of the tank linings, all those years ago. The info I gave you is not quite correct!! Should be OUTER line 1/8 inch , INNER line 1/32 inch, with a 1/4 inch gap in between, There is also lining on the top of the tank, with the same lay out. The tank Scott transfer should look level when the tank is fitted ON THE BIKE!!
