headlight won't come on change bulb and fuse even though neither ever blew what else could it be is it a relay and if so where is it and how do I check it. The bike is a 1998zx9 checked for a short but propably isn't that since fuse didn't blow.
i had a 96 gixxer that had a similar problem it would go out and then come back on. my problem was the plug that the bulb goes into if i bent it down it would work. the connection were not making good contact. not sure this will help but its a start
