In a number of places where there is a table with settings listed they use the following acronym/abbreviation.
Particularly when I am looking for torque settings.
" N/Av" or "N/App"
I thought I saw this explained in their manual somewhere but can no longer find it.
I did look through various threads but once again without any luck.

Thank you.
I assumed that but don't understand why they wouldn't have the settings. In most cases I will use the K75 numbers if they are listed.

Please give us the exact example where one of these abbreviations is used, Shep.

This is one table where at the bottom the filler and drain plugs have the N/Av inserted. My apologies for the reproduction. The N/Av or N/Ap show up in various tables so in this case I will use the K75 torque settings as the filler and drain plugs must be the same on both engines. Why would you make them different?

My Haynes manual (1373) BMW K100 (2-valve) '83 to '92 K75 '85 to 96, page 2 of Chapter 1, shows the Torque wrench settings for the Front fork oil drain plugs for 1993-on 75 models as Not available. So Laitch is correct (not that I doubted you Laitch!).

So I guess Haynes stopped using abbreviations as they were causing confusion?

Trust but verify, as the Cold Warriors said.

It looks like Haynes can't bear to repeat values when they are the same. Instead, those two abbreviations seemed to be used interchangeably to mean "It's the same as the other one you just read a moment ago." If that is the case, it isn't good practice but figuring out why they might have done that is something I can't allow to sap my diminishing brain cells' effort. The BMW manual torque table format is composed in a way to make it unnecessary to repeat values for the differing models when those values are the same.

I use Chilton, BMW and Haynes manuals when I work so that if I hit a snag like yours, I can use another reference. I generally work from the Chilton first. All of them have strong points, depending on the procedure being done. Haynes sometimes has more detailed illustration. I bought the Chilton; the others were offered on line gratis so I downloaded them.

Your extrapolation of torque value for the plug is reasonable and would be reasonable for other parts that seem to have exactly the same composition and application as a different model. Extrapolation and assumption is something I avoid when I can. That's when I consult other published, first-hand sources or the experience of people I know and trust, including myself.

Most of the fasteners are the same, ie. 6mm fillister head screws, and are torqued the same.  It's only specialized fasteners like cylinder head head bolts that have special torque requirements.  You can make a chart of those values and put it on the wall so you just have to look up to see what the torque should be on stuff like case screws.

I have made a list of torque values and laminated it so it doesn't wear out and keep it in the drawer of my tool box with my wrenches.  It has the values for everything that needs to be tightened when doing any maintenance work up to and including clutch spline lubes and valve adjustrments.

As a bonus it has filter numbers and fluid volumes for forks, transmission and final drive.  It is a text document on my computer, so it can easily be updated and printed out if I need a copy.
