Not sure this is a dumb question or not, I have an 07 zx6r starting to have trouble starting. Usually it take one push the bike would start but for the pass couple weeks I have to hold the starter for 2-3 second and give it some gas to start it. Not sure what's the problem here, could it be something clogging the fuel injector? Will adding some gas treatment to clean up the injector help or make it worse?
