I don't want to sound like a smart ar*e, but those nuts are not in safety. You should have one or two threads of the bolt protuding out of the nyloc nut.
If I did that at work I would get a nice big pinapple presented to me from the boss, and if the nut came undone I would lose my job. However it is your motorcycle, so you can do what you like.

Anyone else work in the aviation industry?
