    K3 tank on a K4?

    Is the only difference between the '71 CB350K3 and the '72 CB350K4 gas tank the pin stripping?? I am looking to buy a used tank for my '72 but want to make sure the other years will fit.

    I'm not sure of all the differences, but I'm quite sure the tanks will interchange. The mounts were the same for most of the later years

    I think different years had slightly different seat lengths, so that might come into play... but the 350 crowd would know for sure, better than I would

    Seat & Tank lenghts were different between the CB & CL but not between years.
    You need to match CB Tanks with CB Seats and Vice Versa but otheriwse they will all fit together.
    The exception is the early Seats had a Rear Hinge and later seats a Side Hinge.
    If I remember correctly the hinge change over was 70-K2 to 71-K3 for the seats

    My '71 CB350K tank fits my '73 CB350G and vice versa. I would imagine a '72 tank would be no different. The seat latching setup is different (no lock on the '71) but both of mine are hinged on the side.
