Hammerhead, I have exactly the same setup, with the taller Puig screen and Touratech hand guards. I have tried a few different ways to replace the 450 gram bar end weights as without them, I found that the resonance at 4000 to 4500 rpm turned my hands numb after around 300km.
I really like the TT guards and they are very neatly engineered with the small aluminum adapters for the end of the bars, and I did not want to have to loose them. So, after some experimentation I was able to keep them and re-fit the original end-weights.
In the attached photos you will see that I moved the levers (clutch and brake) inward about 7mm and I used a 16mm diameter washer in the end of the bar for about 1.2mm extra clearance. The result is that the levers still clear everything, the TT guards still clear the Puig screen at full lock and my hands no longer go numb and almost drop off!
Just one more small adjustment to make and that is to clear a little bit of plastic with a dremel where the original end weights screw through the guards and into the end of the bars, this will make it fit nice and flush for that "factory", look, just add a drop of thread lock and we are done!
