Need some fastner help please. The previous owner had track fairings on the bike and checking over all the fastenings I have found some bolts missing and some random bolts! So are all the fastenings supposed to have Torx heads? The aero deflectors on the side fairings have allen (hex) bolts as has the bolt at the front of the tank cover (on its own next to the steering yoke). Is this correct or should these be Torx heads also.
