hi all My latest issue with my flat tracked 1976 Yamaha xs 650 is a now leaking fibreglass tank ! ( due to ethanol mix in modern fuel ?) . So... What is the best way forward in choosing getting a new one ? (It leaks at the lug hole fixing to the seat end , I don't imagine a repair is neither feasible or practical ? ) I feel that I need to offer up a tank to the bike first to see how it looks ...right ? As opposed to ...ordering online Then not being happy and returning paying postage ...? Surely not sir . Then there is ..new in steel £400 ...eBay £10 old , dented requiring refurbing etc and repainting and a lot less for sure ...best way forward I think in practical and monetary terms. Am I right in saying that most tanks sit to the frame by way of the tank seating on the lug/bungs on frame with its elephant ears on the tank ( as what mine doesn't).
