Hi, Mike and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Failed alternator/generator and or voltage regulator.
3. Loose or corroded battery terminals and or cables especially the "NEGATIVE" cable, look for loose, corroded, or broken connectors inside the cable harness at "BOTH" ends.

A 30 amp fuse is a major short circuit. The problem should be easy to find. Trace the + battery lead to the solenoid and check for any bare wire touching anything metal. If all good then disconnect from the solenoid, keep it away from metal and try to start, if the fuse blows then the problem is the wiring between the fuse and the solenoid. If the fuse remains intact then the problem is in the solenoid or starter itself. Reconnect the wire to the solenoid and disconnect the one to the starter and isolate each in turn. This should at least tell you were the fault is. Hope this helped you

You might try to check the horn first by shortcircuiting it ( two leads from the battery.) If the horn itself works , find your way up: check with your contact switched on, the wires that lead to the horn by using a small light bulb or an Voltmeter: if you push the horn button, the licht should go on or the voltmeter should read 12 v.. If not , check the horn switch itself, there could be some corrosion. Good luck , allways a puzzle , the electricity..

Check compression. It may be tired.

Sounds like it is running too rich therefore causing sooting (Black) this will inhibit the spark from igniting the fuel as you need a 14.7/1 air/fuel mix. Suggest you screw in the air screw and count turns, it should be 1 1/2 to 2 turns. Unscrew it back by that amount of turns if you don't have a manual to check?

Also check the air intake is not blocked

It sounds like you have either two live wirers touching or badly burnt wirers somewhere along the constant live from battery to the ignition, or if the engine runs on for a short time it might need to be decoked, if you have added anything to the bike just before this started check the wires from the item.

The float should be free on the hinge pin. Clean the pin and be sure it is not bent. Is the float mounted upside down? Check to be sure the float still floats > If a pin hole , crack or corroded solder seal lets fuel into the float then the bowl will overfill and leak. The float needle is in place isn't it? Please rate my answer. Thanks.

Does it have spark? Does it have fuel delivery to cylinders?
