Check and make sure the battery cables are on tightly with no corrosion. Also follow the ground wire from the battery to the chasis of the bike. You can also check under the gas tank that all the wires are securly fastened with no bare wire showing. The starter should also be tightly secure to the frame along with the cable tight. You might also have a bad battery. Take it to any autopart store for a free battery test. Good luck. If you have any more questions on this year, you can ask me for help.
