I have a 2006 R1200RT with 86k miles that I bought about 7 months ago. The hot idle had alway been rough. Cold idle OK. Did valve adjustment, cable slack,TB synch, new plugs, check for vacuum leaks etc. Long story short, was reading on other forums about stepper motors and how they should reset at each key cycle and not to bother with recalibration via GS-911. Purchased GS-911, recalibrated steppers and idle is noticeably better. Thanks for a great product and I'm sure I will using for many other maintenance/repair things in the future.
