Part 2 ( Too new to post more than 20 pics at a time)
Back of IP. Unsnap spedo/tach cable under boot, pull loose relay? on left.
Remove the two 10mm bolts holding on the IP surround
The two captured nuts on the back of the tray seemed to slide around easily. I popped them out an covered them with electrical tape for a snugger fit. Then popped them back in
Remove the three Phillips screws that hold in the spedo / tach cluster.
I oppened up my IP and did the "button fix" noted above. But i also used the double sided foam tape on the inside of the back of the IP housing on the screw posts. I did this to "snug up" the electronics. Then reassembled the spedo/tach cluster.
I also placed double sided foam tape to the two mounting points for the IP tray.
My first try at this i only used 1 set / layer of 1/2 foam on the bottom the IP tray, however, after a test ride i still had a slight buzz.. so i doubled up the foam by adding strips to the back of the IP to match up with the strips in the tray. Effectively doubling the foam.
I believe at least one source of the buzzing was that the three screws that mount the IP to the tray via the rubber grommets. They are bottomed out on the IP when fully tightened and seemed to be transmitting vibration from the cowling frame to the IP.
With the doubled up foam there is more tension on these three screws and they don't have to be "bottomed out" when tightened to stay secure.
Tighten screws to the point that there is still a 1 to 2mm gap between the screw and rubber grommet when the foam is compressed / squeezed by hand. When you let pressure off the screws should still be secure.
I believe this and the foam tape i added the the crossbar tray mount above fixed 99% of the original problem.
Now start resembling the bike. With each part i re-attached i did a test ride to make sure the buzz was gone and to isolate the source if it did still buzz.
This fixed all my vibration sounds and buzzing!
With any luck this may fix yours too!
