first off, make sure there aren't any safty switches that aren't operating, like the ones for the kickstand, so on and so forth. Next, check all your fuses, one may have blown, you'll never know till you check. The next step will be to check for power on from the istarter switch to the starter relay. If you are getting power from the starter, to the relay, then the relay will need to be replaced. If you are not getting power to the relay from the starter switch, check to make sure there is power getting to the starter switch with the key in the on position. If there is no power getting to the starter switch, make sure that the ignition switch is sending power to the switch. If that isn't working, check to see if there is power going to the ignition. I'll stop there for now, try these things and let me know.
