iman,
Yes that's correct left and right as you're sitting on the bike. The axle has to slide out the left side of the bike. Remove the axle nut on the right side, loosen the rear brake wing nut a few turns counter clockwise, lean the bike onto a comfy blanket or protective surface on the right side cover (protect exhaust, etc.), loosen the pinch bolt and slide the axle out of the left side. You may want to remove the tank, especially if it's full of fuel - before laying the bike over. Try not leave the bike on it's side for an extended period of time. As Darryl mentioned expect some smoke from the right side after assembly and start-up but it should clear in a short time. A few spoon-fulls of oil may sneak by your rings and get into the combustion chamber.
