Get a new sticker?  :)

I use 91 in my R1100S and have experienced  detonation using 89. The R1150R 
is a slightly detuned engine, so you may be able  to use the 89 without 
problem. Do you know how to recognize detonation before it  blows the tops off yoru 
pistons? If not, use the 91. If so, use the 89 in cool  weather and go up to 
the 91 in the hottest months.
