Yamaha dealer won't do this, however a bike shop might.
As I've said in that other thread, get the bd43 wire and make it so the low beam filament of the H4 lights up on lowbeam. (on low beam, it's the one that's currently not lit)
The bike was originally designed for this, but I've heard the Europeans took issue with both bulbs being lit may look like a car a long way off. (to morons, that is...)
So the wire was taken out of ALL FZ6 bikes sold around the world.
Once you've got the wire to which I refer, it's an honest 15mins work to fit it. (that's including lifting the tank)
Lift the tank, plug one end of the wire into the plug in the little rubber boot, have a couple of zip ties to attach the new wire to the existing harness and run it to the H4 bulb. Open the flap on the H4 socket insert the plug and snap closed.
Instantly you'll have both lights working.
Cheers,
Rick
