If you are talking about the phillips/torx screws that hold the white plastic gear indicator on, they are not listed anywhere in my Yamaha manual. They are a 4mm screw with a taper that if tightened to much can break the plastic. Their only job is to hold the plastic in as the o-ring is the seal.
Put a drop of loc-tite on them and twist torque them with a screwdriver handle to tight; no need to bear down on them and make the too tight.
If you are talking about the 8mm head bolts that hold the slave cylinder and housing onto the back of the engine, they are 7.2 ft lbs.
