I'm not sure what kind of bike your working on but here we go, older sports bikes and in line motors:the best thing to do here is remove the body (if it has one) sometimes you can get the socket in without removing the gas tank. best if you do tho it WILL make it easier.New sport bikes: start with the seat remove it then the tank now the airbox, after you have all this apart you should be able to get into the spark plug caps. Be careful here because most of the new bikes use a cap the also acts like the coil, it will have a plug with two wires remove that from the cap and remove the cap from the motor. take your time do one at a time and put it back together they the you took it apart. v twin bikes like harlys and bikes that look like then will have the spark plugs on the side of the motor sometimes under covers that may pull off or have screws. World of powersports is a site that shows micro phish. this is a part break down that you can use to find part numbers and where things are at in the bike. Good luck my friend M.Woodring
