Yeah, 2002Scrambler4x4 is right, you don't have to remove the gas tank for the spark plug, but you do to get to the carb and to adjust the valves when the time come. The gas tank only takes a minute to remove, and if you do it is a straight shot to the spark plug.

 

oh yeah you do have to at least move the tank believe me its a big pain.....rooks right werent using their thinking caps but at leat doesnt burn plugs like a 400 does
