Have the Works Connection unit on my new 2006 and I am pleased. Have owned several WC plates. Good motor coverage and takes advantage of the OEM Yamaha mounting design. A friend installed it for me initially, thus my question. Is there supposed to be any type of spacer between the frame and plate at the rear single mount? There seems to be considerable space between the rails and the plate. Yes, you can eliminate some by tightening the 8mm, but I am concerned about too much torque into alum. threads. I suppose one could use blue thread lock and live with it. Anyone? Thanks.
