I would adjust it so the low beam was where you want it. When you switch to high beam, the low beam is still on so you have all of the field of vision of the low beam plus the addition of the high to reach out a greater distance. On my old bike, when you switched the bike to high beam the low beam light turned off. I don't see the problem you are having.
I do have the low beams adjusted. The problem is that on a dark road at night, the high beam does not illuminate the road at all....just the sky. In other words, it is of absolutely no benefit
. The low beam isn't bright enough at speed, say 55-60 mph. so I need a high beam.
Most of my other bikes have a high beam that actually illiminates the road, along with a low beam that also works. The problem is that they seem to be interconnected, i.e. i can't adjust them independently.
I think I will adjust the high beam to factory specs, perhaps a slight bit lower, and then leave it on all the time. Kind of a tough alternative, but???
I can't tell from the limited replies if noone else actually has this issue, or, if most just don't ride in the country at night. I will probably take the bike back to the dealer and ask for a fix, based on safety. Not sure what he can do though
