sorry for the dumb question but where the heck is the spark plug on a 2002 trail boss 325? Is it under the air box and fuel tank? This is my first polaris atv. It's not idling from sitting. I put seafoam in the tank and have been riding it hoping it will clear up on it's own. thought i would change the plug but can't locate it. Thanks Brian

If it's not idling your problem is in the pilot jet. Just order a new one and replace it.

Ok, since you don't seem to take advise very well, yes the plug is under the tank. Your welcome.

I give you advise and you respond like no one had said a thing. If you don't tell us then we will never know. What I mean is yes the plug is under the tank, kind a pain to replace but, your problem does not lie in the spark plug problem if it runs fine in higher RPM's. If a bike won't idle it is in the carb. Take the carb off and take the 3 or 4 screws off of the bottom of the carb which is the carb bowl. Then once you have the bowl off right in the center of the bottom of the carb is the main jet that sticks down the farthest. Right in front of that should be what looks like a empty hole but, with a small flat head screw driver go inside that hole and unscrew the pilot jet replace it with a new one and reassemble. Problem fixed. Sorry if I came off rude but it wasn't like you acknowledged what I said.
