I need some guidance please, for my 1955 A7SS:-
Head gasket - Looking at the parts book 1954-57 edition for 500cc and 650cc bikes, the part number for 'A' Group (Plunger and Swinging Arm Frames) is 67-255. I can not find any other numbers for a 1955 A7SS, so am I to assume that this gasket fits both A7's and A10's?
