The terrible gear grinding sound is probably the starter system - if the battery has not been freshly charged it will not have enough power to run the starter relay/starter solenoid/starter motor/etc.

If the bike has not started then the exhaust pipes are not hot enough to ignite unburned fuel; so the backfire could be fuel igniting in the combustion chamber when the exhaust port is open - which could be a timing problem. Just thinking out loud here. Is it a points system? Perhaps, if so, a little attention there might free things up. Just guessing.

Sticky valve maybe? Or the exhaust pushrod is adjusted a little too long?

ignition timing off 180 degrees = timing rotor placed wrongly

single fire or dual fire? maybe double check to make sure the wires are on correctly? the gear grinding could possibly be, if it has electric start, that the starter isn't disengaging correctly.
