Some problems like a dirty start button switch can cause this but there are others that are very comman.
You must check your battery for proper voltage. Non running it should be high 12's or low 13's.
Bike running at idle should show just over 13 volts. at 2500 to 3000 rpm you should see 13.8 to 14 volts.
Your starter might be getting old & the brushes are most likely worn down. while cranking, your battery voltage should not drop before 10 volts. If it does, your battery could be weak or your starter is drawing way too much power because it's tired!
Dirty or loose connections on your main power wires from the battery to the relay & down to the solonoid will cause high resistance & add to your problems as well.
If ya cant fix it with a hammer, it's prolly lectrical
