After six months of trying to solve an intermittent brake failure problem I replaced the front ABS sensor on my 04 1150 Gs myself and solved the problem. Dealer computer could not figure it out so I feel pretty good. Add that to fixing my own flat on my 1970 r60/5, replacing a broken turn signal on the Gs changing all the fluids on both and the tires and brakes makes me feel pretty good about my wrenching abilities. These bikes are not that hard to work on once you get into it and take your time. Other than a few stripped bolts and a few bruised knuckles I got it done. Can't imagine how much money I saved over dealer service.
