be careful when trying to undo them as the splines can easily round off if the nut is a bit stiff. if i were you i'd try plusgassing them the night before as if the splines round off and/or the nut is seized they are a bit of a bitch to remove.
just spent a very unpleasant saturday night hacksawing, molegripping and drilling the f*cking stock bolts and well-nuts out of my top fairing.
