Your engine is gone. Sound or not it's dead.,

Wrap the wire round the Ht lead two or three times, it induces a signal to the Rev Counte, the wire does not have to be bare or connected to anyting other than wrapped around the lead..

Ground (negative) cables are usually black

If the bike only run when choke is on you may have have a plug metering jet. Small jet located in the carb body near the main jet.Jet could have unscrewed from carb due to vibration.

If the engine is turning over, then the battery is probably ok. I would suggest put the choke on and crank it over. If it does not start, then hold the throttle wide open. If it gets flooded, then this will allow enough air to level out the fuel. When an engine is flooded, it is best to hold the throttle all the way. The bike should start. If not you might spray a small amount of starting fluid in the air filter then start the engine. Don't use too much starting fluid. Just a small shot.
