Either low battery or the solenoid/starter is going bad.

  • Follow the thick red cable from the battery and it should take you to the solenoid

quite likely either the killswitch shorted out or the starter solenoid has taken a dump. you can cross the posts of the solenoid with a screw driver with the ignition in the on position. if it starts then you have a bad starter solenoid.

Hi, I would take it apart to free the clutch, there is another option that may work but thats up to you, put the bikes front wheel against a wall, put in gear hold the clutch in just to put presure on it, press the starter,all the best.
(Just to say I would always advise some one else to take it apart)

I once had an issue on my CB550 when I turned right I'd blow a fuse. It turned out there was a frayed turn signal cable. Every time I turned so far the wires shorted. Look for bare, or frayed wires near your left front turn signal.

You have a hole in the water jacket that surrounds your exhaust, usually on the bottom you cant find it till running on the lake or have water hooked to the engine for on land running the engine
FIX hook up the water at the back its a hose fitting and turn the water on it should cycle through the motor and exhaust possibly revealing hole but turn it on and it will start squirting some where?? take off the whole aluminum exhaust /water jacket, take it to a welder that does tig weld on aluminum , usually just a patch. back in and off ya go. OH And drain it more next time! avoid this with a good tilt...

Remove and clean battery cables, if that does not work look at a replacement battery. Another test is to turn headlight on if possible and observe, if it goes dim replace battery.
