you dont unscrew the cover,you pull the plug wire to access the plug and then use an extension with your socket

When you buy the new spark plugs, take one of the plugs and get a spark plug socket to fit. The size may depend on the brand? Try 5/8 spark plug socket. Hopefully the socket for the new plugs will fit the old plugs?

The socket is an 18mm Sparkplug Socket for a 12mm thread plug.

pull off plug grabbing it as close to spark plug as you can. Using socket rotate counterclockwise and remove plug. Be careful putting plugs back in and thread by hand first. Then torque as plug box says as it depends on if you have a washer or not.

Hello, I don't know what size the socket you will need, but an easy way to find out is buy the spark plug(s) that is recommended for your bike, then go to an auto parts store with your plug, and find out what size socket you will need.

if its your first time you need a haynes repair manual.you need a spark plug boot puller.you need 3/8 ratchet wrench.spark plug sockets.from size 5/8 to 13/16.you probably need size 5/8 socket.you need extensions different sizes.and universal joints.to reach hard to get plugs.you need torque wrench. and spark plug gap set.

Changing plugs can be rather simple or very difficult based on the ability to access the plugs. If there is alot of room, get yourself a rachet and plug socket, and starting with one plug, remove the plug wire, remove the plug, and replace. Install new plug, tighten, and install plug wire. Move on to the next plug. By doing them one by one, you reduce the chance of crossing plug wires, ect. Its easiest to start with the drivers side front, and end in the passengers side rear. That way you know you got to all of them. Good luck.22

60,000 miles is the replacement interval, and when you replace them, buy plugs from a dealer. "Aftermarket" plugs do not work well, sometimes, they make it run worse.
