Appreciate the vote of confidence but there are a few others who are likewise knowledgeable if not more..
On to your concern, it would seem you have two (2) issue, 1st if wont crank and the second will crank but not start.
No Crank: Due to the massive current required by the starter a component is installed between the starter button and the starter. This component then switches the battery to the starter motor. In cars this is the starting solenoid, in most bikes, this is the starter relay. Normally in the starter relay there would be 2 big terminals for the battery and the starter motor cables with 2 smaller wires for the starter switch and ground. Try this - try pushing the start button with the headlights on, if the headlight dims considerably, then the starting relay is good and the motor is bad; on the other hand if the headlight dims just slightly or not at all, it is the starting relay (the one with the clicking sound).
Most starter motor problems could be:
1. the bearings/bushings at the ends of the armature;
2. carbon brushes;
3. commutator segments (the multiple small copper plates that the brush contacts with).
However, it may be to your advantage to simply replace the motor should it be deemed defective, difficult to secure parts or not economically reasonable to go down component level repair.
Will Crank but not fire: There are 2 major requirement for a gasoline engine to fire, fuel and ignition. No fuel could be verified by removing the air cleaner and pouring a small amount of fuel down the throat, start the bike, if it start and runs (even for just a moment), you have verified the fuel problem. No ignition could be verified by removing one of the plugs, reinsert the high tension wire plug to the sparkplug and place the sparkplug atop any metal part, crank the engine, there should be a spark at the plugs.
Pls post back results whether fuel or ignition and we can go further from there.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.
Good luck and kind regards.
