My right hand drive K11 takes more than 3 screws...
I believe the 3 screws described above are the ones at the bottom of the cowling.
Right hand screw, no problem.
Middle screw. Can see it between the cowl & the plastic cover that goes around the steering column. My K11 doesn't have an adjustable column so there's no way of getting a screwdriver at it. Remove the covers that go around the steering column, 4 screws underneath.
Left hand screw totally hidden. First remove the trim around the heater controls / radio /vents = 4 screws.
Once those threre screws are removed, the cowling can be lifted out.
You can unscrew the instrument cluster (more screws), disconnect the speedo cable & electrical connectors & you'll then have the cluster in your hands. You might not have to do this if you can reach behind & get at the bulb you need to change.
