For years I have greased all nuts and bolts on assembly, with the exception of wheel bolts. Never had a problem and they are always easy to undo next time.
However, I now have two things I never had in the past: the Internet and a torque wrench.
So, apparently using (lithium) grease on a fastener:
is a good thing because it overcomes friction which would decrease torque values
is a bad thing because it overcomes friction and will increase torque values
doesn't matter because my torque wrench is wrong anyway
doesn't matter because manufacturers allow safety margins in the torque figures
doesn't matter because in any case my handlebar mounting bolts are going to snap, my rear shock will break along with my drive shaft, my rear brake will seize, my electrics will get on fire, and my rear wheel will fall off. AND my rear shock stud, which started this train of thought in the first place, will snap (though I do now have a support for this stud, courtesy of Sidecar Paul).
