    CM450C Fuel Tank compatibility

    I just acquired a 1982 CM450C that is in rough shape. The fuel tank is in terrible shape and a hole has rusted through it and the metal is thin enough to compress with my hand so I will be replacing it. A local guy has a CB360 tank that seems to be in good condition, but he doesn't have specifications listed and hasn't responded yet. Does anyone know if the CB360 gas tank will fit the CM450C without major modifications?

    Thanks,

    Lonely

    The tunnel of the tank, part that goes over the frame backbone, is too narrow on that tank. The 1978-86 400/450 series has a thick section in the backbone that most bikes don't have. Here's some help https://www.hondatwins.net/forums/67...ank-sizes.html
