Wind deflectors or sidevisors as fitted to the mark 2 Burgman.
Look at the above three pictures, the top and middle pics show exactly where the sidevisor has to be positioned. Next mark with a felt pen through the top 4 mm hole in the sidevisor onto the plastic body. Carefully drill a small hole say 3 mm in the plastic and gradually open it to 10 millimetre. Place a rubber inset in the hole and loosely fix the visor with the 4 mm bolt. You can now accurately position the sidevisor at the bottom position carrying out the same procedure for drilling the 10 millimetre hole. When you have the top and bottom 4 millimetre bolts partly screwed in start at the middle and peel off the self adhesive backing tape. Finish off by tightening the 4 millimetre bolts. Job done !
