What size bolts are used to attach the carb float bowl on a 1975 Honda CB360?

After doing some research online, it looks like they are M4x14 but I want to double check.

4 x 14mm
thread pitch 0.8mm

Buy them from a Japanese motorcycle dealer or online parts store.

Your bike and the CJ360 use the same carburetors, with a few minor differences.

My book says 6x16. They are cheap just get both, one of them is right.
