Some F7's (I suppose f5's) had thinner (silver or metal looking) handlebar clamps. These are thinner and weaker than the black ones found on previous year Sno-Pro's. The service bullitin will replace the clamps with the same clamps (black/thicker stronger) found on last year's sno-pros.
If you don't have black handlebar clamps, it would be a good idea to go to your dealer and demand that AC replace them with the update. My left one was "broke" and I discovered it when installing the isovibe. The dealer and cat replaced it with the black sno-pro version.
