Here's my take on the subject.
Ordered SW Motech engine bars from NN on the 1st.
Rec'd email from Norman on 2nd. letting me know that the bars were on their way.
About 17:50 today (3rd), bars arrived.
Had my tea then laid out all bolts/spacers/washers/nuts that came with the bars, then set about fitting them (19:15-ish.)
Finished fitting about 20:30.
This time included having to remove and replace the bash plate to retrieve a spacer I had dropped.
Also included loose fitting the bars then removing all bolts and refitting using Locktite and a torque wrench, as recommended.
All this whilst grovelling on the ground. Us old chaps don't have lifts, you know.

The result is shown below.
Not exactly the hardest job I've done on a bike
The subject of fitting engine bars to the engine cases seems to have started some discussion.
There's my ha'penny worth.
If BMW leave threaded blank "holes" in their engine cases, then surely someone is going to make an accessory (in this case engine bars), which will screw into them. It's not as if they even blank them off with a plastic bung.
I imagine that, as they leave them open, they expect something to get fixed to them, and so make the engine cases capable of taking a little strain for want of a better word.
Just my thoughts. Perhaps someone in the Austrian factory had a little time on his hands and thought that he would drill some holes and, just for fun, run a tap up them, then sit back and see what transpired. Then along came SW, TT, Wunderlich etc etc.
