I changed my oil recently and accidentally loosened the wrong bolt on the bottom of the crankcase. My skid plate has two holes in the bottom and instead of breaking lose the rearward 6 mm Allen drain plug bolt, I loosened the 6 mm bolt that is more toward the front of the motor. This bolt acted weird and didn't want to back all the way out it seemed. That is when I realized it was the wrong bolt and tightened it back up. Can someone please tell me what this bolt is for? I know it is probably fine but just wanted to make sure. Thanks in advance.
