Moving controls. What is easier?

It's not hard to drill the bars.  It's not rocket science, a monkey could do it.

It's easier to not drill them.

Do what you feel is within your capability.

If you feel you don't have the ingenuity to make modifications out side of factory spec work properly and safely, don't do it.

Also, if you are going to be drilling the bars, with most adjustable bars, you may loose some range of adjustably...FYI.

I'm pretty sure the reason for the nubs are to ensure assembly consistency on the production line.  If you look close you'll also see a couple index marks on the OEM handlebars where it sits in the clamps.  The OEM clip-ons on my R11S also have little nubs which line up with the slots in the upper triple clamp.  There are also sorts of discussions on the purpose of those nubs, but they're too small for any other purpose, and we all know clip-ons dont need any extra help to hang on to a fork tube.
