So a johnson bar multiplies torque by magic? Note I said it wouldst amount to much with a crow foot, just use some caution not to go too far and break it. Changing the anger of the wrench shifts some of the force from radial to axial and so reduces accuracy of the torque wrench. (Don't know about you but a little explanation helps me understand and remember.)

on a single nut or bolt it wont matter.. if it is a head bolt on an engine then use the same method on all the head bolts so they will all be the same...or anything that has multiple bolts...I was a auto mechanic for 30 years. (GM) trained.
In other news, I posted this question to a forum specifically for this motorcycle and the answer there is "we don't need no stinkin' torque wrenches" - TFAR! Or just plain "TIGHT" in capital letters.
Gunnery, gunnery, gunnery. Hit the target, all else is twaddle!
It’s fine, 90 degrees is correct so the moment arm increase is minimized.
The truth is torque isn’t really that accurate of a way to consistently tension bolts. Use some thread locker or lube and your bolt tension goes way up for the same torque reading.
Torque is used for mechanical design all the time, for structural bolting we require other methods as torque is pretty inaccurate/inconsistent unless calibrated by testing.

Yup. Bolt stretch is key to holding tension on the fastener, generally speaking index angle gets you there. Torque is just a quick and dirty way to get you in the ballpark.
