Hello everyone i am new to this forum and new to the honda world and i am in need of some help i have a 1980 cb650c and i need to replace the fuel tank. It has rusted out and leaking. I really like the looks of it but i cant find one that matchs it. Can i put a (750,knighthawk, or another style tank) on it with out having to modify the frame or the tank? Any help will be muchly appreciated.
