In today's video, you will learn how to remove and replace the engine spark plug on a Royal Enfield Classic 500 motorcycle, which is single-cylinder. In this case, the spark plug is already visible, so you will not need to disassemble any part of the motorcycle; simply remove the spark plug cap to expose it, using a socket wrench with an extension to unscrew it. Now replace it with a new one, ensuring it has the correct heat rating and the same thread pitch, screwing it in by hand before tightening with a wrench (preferably a torque wrench); reinsert the cap and start the engine!
