Hi AndyS
Congratulations on the purchase of your GS-911! The GS-911 is a diagnostics tool which allows the clearing of fault codes after the fault has been rectified. As you are removing the lamps for the track day, the fault will remain present until corrected.
For most track bikes (S1000RR, S1000R), you can disable the lamp warning within the cluster menu, I've included a video on this below:

Kind regards
Ruan
