Can not start

Sounds like you need to check the generator and charging circuit.

The bike will start and run on the battery alone until it is drained.

Once a bike has been started the battery power is taken over by the generators power this also replenishes the power lost in the battery when the bike is initially started. If the generator does not generate power the bike will continue to us the power from the battery until it is exhausted and will therefore stop.
A simple test is to turn the bike ignition on and turn the headlamp on (check the brightness of the lamp) Start the bike and re check the brightness of the head lamp, it should be a little brighter if the generator is working. Another test is carried out with the use of a voltage tester (multi meter). Set on dc volts test the batteries voltage eg 12vdc, start the bike and re test the voltage should be around 13 - 14v dc if the charging circuit is working

The problem is the side stand cut out switch - it allows you to start the bike to warm it up on the side stand but if you true to ride off with the side stand down the bike will cut out reminding you the stand is down.
If you bike is cutting out when putting it into gear after starting it is definitely the cut out switch - check the side stand there will be a switch around it some where close to were it bolts onto the frame.

I have a bike that at one time I'd be riding along, and the motor would die, and all lights and instrument go out, as if I turn it off with the key.

Turn key off, back on, and all would be fine until the next time.

It turned out to be a bad ignition switch.

first try a new spark plug, if you get spark check gas filter, have spark ,have fuel, have timing it should start

fuel air is my first thoughts

• NOTE: A rich problem gets worse as the engine heats up.
• 
  
• NOTE: A lean problem gets better as the engine heats up.

you need ajust the floats in the bole to let more fuel in

It may be a safety switch in the clutch lever or bike stand switch being a bit sticky or broken wire in the wiring harness near the steering head that bends alot.

Hi,

If you haven't put a new, properly charged battery already, do so.

Good Luck and Let me know,
