Failed after 150,000. Lasts 1-2 hours. These are the steps you need to take. Remove airbox, remove fan and fairing, remove serpentine belt, 17mm nut for rear electric nut, remove electric clip, remove top 16mm bolt (on idler pulley) , loosen the bottom 16mm bolt from below, then hit the bolt with a hammer as a nut pulls into the body, unscrew the rest of the way out. Or take out the generator. Turning back
