I've got a fully charged battery, changed the starter relay, put in new spark plugs, oil and filter is still fairly new, the chips in the fuse box are still good, and all of the wires seem to still be intact. When I try to start the bike, all you can hear is the engine TRYING to turnover. I'm not sure what is wrong with it. Could it be the carborater or something wrong in the engine itself? It is a naked streetfighter zx6r if that helps in finding what type of problem I have.
