Yes, because you flood the "bathtub" the cam lobes set in . It's a good idea to use fogging oil (sprayed in the sparkplug opening )to the cylinder to lube the rings and cylinder walls as they are dry and won't see any oil until the motor actually starts , jacking and turning the rear wheel with the bike in gear will make sure the  piston rings are free and the cylinder walls get coated, and may fill the oil passages in the motor.
