And what kind of fuel cap goes on? That question is asked because apparently it is not a Guzzitank. That is not really necessary, because it comes on a machine that is at best very classic, and certainly not purebred: A tribute on a budget basis to the British twins with rigid rear frame from around WWII.
If there is a reader who knows what this tank is intended for, the owner can go on a hunt for a fuel cap.
That he is also looking for a pair of wire wheels for an XS650, that may be clear ...
Thanks in advance ...
To identify the tank, photos of the bottom are indispensable.
