YEP! Ed´s right.. check ALL connections.. Solinoid terminals,Take the starter button right off the bars.(2-3 screws underneath)blow out the copper contacts in there.. maybe spay some contact cleaner..LOL I know my horn botton cuts out all the time if I don´t use it for a while. ;D if it don´t turn over.. solinoid´s toast. get a buddy to hold the starter button on and place a screwdriver on the BIG terminals on the solinoid will make it crank if the starter´s ok..if no turning..starter may be gone.. OR the main fuse on the battery. Also check the juice from your battery. If it´s too low/old, it´ll just make a funky/buzzy noise. Boost it off a charger or another bike battery. NO car battery!! I´ve seen wire harnesses light up from that. NOT cool.. (:o LOL Good luck man!!
