Some areas are judgement calls. Warning, this comes from my days of wrenchin' in the '70s. Don't know about modern stuff.
Honda handlebar clamps have one end which is a bit longer than the other, as indicated by arrows, or tiny punch marks. The taller/longer part is always fitted to the front, or leading direction. The bolts in those are torqued to spec. The rearward, backside, bolts provide the controlled clamping.
The factory setting for the backside, clamping bolts was to provide sufficient clamping force to keep the handlebar from rotating during normal usage, like from rider weight bearing down. However, the clamping force should be light enough to allow the handlebars to rotate forward during a frontal impact, like when the rider's knees/thighs *bonk* into the thing.
This is a combination of rider safety, and reduction of recoverable equipment damage, as in being able to re-orient the handle bars and ride the bike home.
The left-hand and right-hand threaded mirrors is another. The locking nuts are torqued down enuff to keep the mirrors in place, but to also allow release when *bonking* into other immovable objects. Again, swing them back into place, and go on your way.
For motocross and dirt track, it really helps to adjust the clamping force on clutch and front brake lever perches to allow them to rotate on impact. Saves the levers, and the rider can quickly re-enter the race. Just torque them down enuff to stay in place during normal riding.
How much torque here? Are the handlebars chromed, or aluminum, or stainless, or painted, or serrated, or rusted?
Judgement call. Clamp down and test...
