I have a 2011 R1200 RT, your UBS GS-911, and a TwinMax Sync tool . I was told I had to get something zeroed first using my GS-911 before balancing with the Twin Max. Could someone please explain what that "something" is, what does zeroing it mean, how do I find it within the GS-911 program, and how do I do it? Thanks very much!
