Default Changing the Spark Plug

I know this is a stupid question but can anyone tell me where the spark plug is located on the YFZ 450 and the easiest way to change it.? I need to change it and I cant locate it without taking apart the atv.

Its under the gas tank. Just take off the plastic that goes around the tank remove the tank and the plug will be right under the tank.

Thanks. Do you know the number of the spark plug so I can pick one up before I start to work on it?

Make sure you take an air blower and blow out the dirt in the hole before you take out the plug. There is a small hole on the side of your head to do this

Is this the same as the yfz 450r? If so that seems like a big pain just to check your plug.
