How do you change the spark plug on a 2009 kx250f?

first you remove the four bolts out of each front shroud on the gas tank. next you take the two ten millimeter bolts out of the rear side panels. after that you remove the seat and detach the tank from the bike by removing an 8 millimeter screw up by the steering post and a rubber strap at the end of the tank. after that disconnect the fuel line from the left side of the carberater and take the tank out. after removing the tank you can see the top of the motor and then pull the spark plug cap after that insert the tool provided with the owners Manuel and twist the plug out. then when putting the plug in make sure you crush the crush washer on the new spark plug and after that plug you cap on and do all these steps backwards and your set.
