Odd about the torque - unless I am missing something, my manual doesn't have it listed at all. For the R65 it only goes to 1980. And for the years it does list, it shows different amounts for each side (higher for the right?). Have you heard of that? I'll have to check Snowbum's site and see if he mentions it.
Ah.....The problem is translation from the original, slightly corrupted Romanian, that was then translated into Hungarian for the benefit of the guest workers in the BMW factory.
Finally the resultant word porridge was translated to German and lastly into English.
For all bolting of 10mm and above the simple German torque figure of "Gutandtight" will suffice.
The English is less precise, measuring between one half and one full "grunt".
The Australian edition contains the additional incantation "Fu$k You" for those occasion when the shifting spanner you were using instead of the approved single hex box spanner (made by Heyco or Stahle Willie of course) slips off the nut or bolt in question resulting in loss of the outer dermal layer of one or more knuckles.
