Hey guys going to oil change her. I’ve noticed the detent plug where the spring and bearing is weeping. Is there a copper washer sealing it? If there is is it worth changing? I’ve heard some horror stories about removing it I’m pretty sure the previous owner has been doing the oil drain from here as the sump plug looks like it’s never been removed from factory If I leave everything as is am I still able to drain oil by removing the filter screens, and laying bike over?
