First, Is the battery well charged? 2nd, check all connections for corrosion. 3rd, Check the kill switch. Don't know if there is also a switch on the side stand so you can't start it with stand down (my cbr has this and they do stick sometimes). Have you checked the spark plug? Use a long screwdriver in the plug cap and hold the other end close to the engine so the metal shaft is close but not touching the engine and turn engine over. Should see or hear a spark between screwdriver and engine. Then it is definitely plug. If not, next thing to check is ignition coil to see if that has power (follow plug lead to find this). If no power to coil you will need to check connections and if still no luck it is probably the electronic ignition. good luck!
