Does the starter have a solenoid on top of it? or a starter solenoid elsewhere? If it has solenoid on top of starter, it does two things, 1 energizes coils in solenoid to complete circuit to starter motor. 2 pushes starter motor pinion gear out to mesh with large gear on clutch. The battery cable comes down to one side of the solenoid. A heavy copper link from other side of solenoid goes into the starter motor. A smaller gage wire is in the 'start circuit' and 12v + must be sent to solenoid through this wire, live only with ignition sw. on and engine run sw. on and starter button thumbed. The other solenoid could look very similar to type used on automobiles, small black cylindrical with a mounting bracket at least one small terminal and two heavy brass bolts, one on each side. one side of the solenoid coil is most likely grounded to mount bracket. 12 v. + applied to sol. coil closes heavy contacts to brass bolts and starter gets current.
I would make a long jumper wire, go from Bat+ to the terminal screw or connection to small wire on solenoid, by-passing ignition sw. engine run and starter button. Or jump bat. side of solenoid to small screw with piece of wire or screwdriver,If when system does not work as it should, hook jumper to bat+ other end to sol. screw with small wire. if sol. clicks and starter cranks engine, then there is an intermittent open in the starter circuit, also if the engine run sw. is bad, it could cause no power to go to the ignition circuit. What happens is a hot wire or 12v+ goes to engine run sw. when 'on' it sends power to two places, one of those places is the coil and points, the other place is one side of the starter button, when starter button is thumbed, power comes out of its other wire and over to the solenoid coil.
On some bikes, safety interlocks are in series, kickstand must be down and/or clutch must be held in, these switches if broken or not activated will/could keep starter from cranking the engine.
