Dumb question and this is my first ATV. I'd rather ask here then at the dealer.............Where is the spark plug located? I've changed spark plugs on mowers, snowblowers, etc.... Just need to figure out where it is. 2003 AC 400.

 

Should be right hand side (sitting on machine) top end of motor, you will see the plug cap and wire going up to the coil.
