Found All the rest of them....chain cover...It's used in two places. One on the right side of the crankcase just behind the cavity where the timing chain runs. See 3-80 in the service manual or 3-81 in my rework. It's used with a gasket washer. Search for "Fit a new gasket washer to crankcase bolt A." The other is one of four bolts that attach the sprocket cover.
Thanks,soon or later I will find my setup"Found All the rest of them....chain cover... "
Not sure where you are. The outer cylinder head bolts are M6x50 but they have a 5mm hex socket drive AFAIK. See the bottom of 3-98 (or 3-99) in the service manual.
Good luck on finding space for everything.
