From memory, so beware: The BMW manual tells you to remove or loosen the chain guard so you can get to the little screws on the rubber swingarm protector. You remove those screws, which go through some little dished washer dealies, then you can slide your 6 (or was it 12?) inch extension tipped with a T50 Torx head under the rubber. Might want to first clean out any grunge that's collected in the bolt head. Seems I had to the countershaft sprocket cover as well. It's not rocket science, just more work that you think it should be. Makes the beer taste better when you're done!
