I don't know if this has been discussed or maybe I have bad luck. I was replacing a cover, the one with 13 bolts. I got to one of the bottom bolts, and while tightening it I heard a snap. Suzuki must make these covers very weak because I was taking it nice and slow. It cracked pretty bad right around the bolt hole. Now I'm trying to fix it with Jb Weld. I had 12 bolts in already and the last one cracked. Maybe because the part was used?
