Yeh there is, but I don't have my owner's manual here right now to even tell you which one it is. If no one answers you before late tonight I will post it.

 

OK the oil plug for the counterbalance is.... Take the middle skid plate off the bottom of the atv, you will see the starter ok looking from the front of the atv toward the back, the plug will be directly behind the starter in the middle of it. The plug to the right is the crankcase, the one to the left is the recoil housing, you want the one in the middle. The plug right beside the starter to the left is the starter pinion drain plug. Good luck, hope this helps.
