Re: '78 CB400



Do a search but I think the coil on this bike is the same as the ones from other honda bikes of the same vintage.. There are a lot of parts that cross over on these to like CX500's and some of the 750's etc. You may be able to run one CB750. I have not needed to replace mine, and I have a spare, but some other parts I have and I could find them listed for other bikes easier than this one. Check the fiches for the CB400 and get the part # and see if it matchs one on the CB750 or CX500 etc.
