You probably need a new clutch. That can explain why it bogs. The smoke I don't know.

Hi Bryan, it does sound like the battery, if it is a 12 Volt system, just connect a set of jumper leads from a 12 Volt battery, another bike car etc. and see if it makes a difference, i think you will find everything works fine with a new battery.

weak spark can indicate bad coil,,,correded wires,,,or grounding of the ignition circut,,in which case you would have No spark,,,simple things first,,,check your wired to the plugs,,some have removable plug caps,,and many times,,corression interferes with strong spark,,,coil testing must be done at a service provider,,,wires can be grounded,,expically if you have dumped the bike and the handle bars have be dissloged somewhat,,,check the kill switch for damage inside..

Replace the magneto/stator, CDI and voltage regulator/rectifier. Usually if one messes up they all go bad.

solenoid needs a diode across it with stripe on positive side.

can be a vacume air lock try open fuel cap to start cold to see if starts?

or sounds to me that the orfice is to small on the cold start port or dirty ...not enough fuel due to your hand choking

other is a air leak between carb to intake valve/port

when engine running spray some WD-40 around intake gaskets to see if rpm picks up if do its leaking

If there is a number on the lock itself, you might be able to get a key punched out.
A couple other things to do, take a 1/4 inch drill bit and drill out the lock, turn with screwdriver, should start right up, second, carefully take apart the bike, getting to the keyguard and remove the lock, then take the lock apart, get it re-keyed..
