It would help to give an accurate answer if we knew what kind of bike your buddy has, to start with. Year and model?

The YZ450 uses an angle torque specification:

Apply Moly Disulfide grease to the bolt threads first.

Then, run the bolts up evenly to 22 ft/lb. and then remove them.

Reapply the Moly Disulfide grease to the bolt threads.

Tighten the bolts to 14ft/lbs.

Mark each bolt and rotate each one 180 degrees farther in two 90 degree steps.
