Now I dont want to start a wave of people stripping their motor threads, but just saying... I fitted an IOSD mini to my P2 this week and when I fastened the arm bolts and screws to the lid, I decided (for some reason) to nip up the motor bolts too. I was surprised to see that there was a good 1/8 of a turn available on each one. That is a bit odd since they are probably locktited. P2 is a month old and done about 15 trips.
