From it I got answers to two questions, one of which seemed to be befuddling others.
The location/position of the Cylinder Head Cover Plate (that was in the way of accessing the seat nut) ... According to this manual, it appears to be on the right rear cylinder and the lip is facing upwards at the rear, thus getting in the way of accessing the seat nut.
The PO gave me this little bag with a very small allen wrench and screw...he said he had no idea what it was for. This manual explained that.
Both above answers are on page 8 of the manual.
EDIT... here I go, getting my left and right mixed up .... I meant to say LEFT above...am I right?
