I changed the stock high beam bulbs to Osram Nightbreaker Plus high performance bulbs. What a PITA. I have large hands, and the right high beam proved to be a challenge. The harness for the heated grips was in the way, the top right shelter was in the way, so I ended up removing the top right shelter which I was going to do anyway for my Speedohealer install next. I had to access the VSS between the frame and right radiator.
A pic of where the Vehicle Speed Sensor is located. This is where the Healtech Speedohealer connects to adjust my speedometer and odometer to read correctly. Mine is in metric, and reads 6% fast.
