Default Motor Tear Down after crank got stuck

Hi there, I got this 80 cc two stroke I tore down to find out that the motor seized inside between the crank case and the crank. I believe what caused it was bearing failure but I did not see any broken parts when I took off the cylinder and Piston. I also noticed that inside the crank case it was bone dry. For future reference I ask if it would be ok to put a couple ounces of oil or some thing like pro long or dura lube for inside the crank case lubrication.
