I'm kinda new at this and I'm trying to figure out how to drain my chaincase on my 02 Legend so I can replace the lube. I can see under the belly pan the opening that gives me access to the drainplug but can't understand how to remove it. There is a small round opening but not a hex that would take an allan key or something. It is not raise to the point that I could get a vicegrip on it either. I don't get it. Anyone?
