Engine Top End:
Auto Decompressor Bolt 104 in·lb
Cylinder Head Cover Bolts 87 in·lb
Cylinder Head Bolts: M10 36 S
M6 104 in·lb S
the S in that means the specified pattern ... just like tightening car tire bolts... please note all that it its INCH lbs....
don't know why it says just 36 for the M10 bolts unless they left out inch lbs
