Pretty old thread going on here but I just picked up a 07 shadow 750 and noticed a little seeping coming from what I believe to be the same area. Until I have the time and money to do the job, is it okay to ride in the meantime?Someone else had asked the same thing a while back. The oil normally drains out the right side where the cam chain opening is on the rear head.
So when leaned over to the left it can pool against the cover seam and after years the gasket or sealing material is seeping.
Mine has seeps from the rubber cam plugs.
