went to change the oil a couple of days ago. removed the nuts and female (sex bolts) that hold the skid plate. one of the rubber grommet studs fell off the bike. is there a trick to replacing this stud? i have the part # on the broken stud, but want to make sure i perform this repair correctly. yes, i have crash bars on the bike and a secondary Touratech skid plate that all attach to the studs. should i change all of them or just the broken one?
