Oh Mama! You have fixed me! Many thanks,all. No, I have a 2008 1800 - - -Need a new pic. For future reference, the adjuster knobs/wheels/12mm adjusters that look like gears. can be adjusted with your fingers by reaching down between the tank cover and forks. Will have to see why the 'dial' adjuster isn't working later. For now, I'm fixed.
Also, high & low beams DO adjust together. One adjuster for right side, and one for left.
Again, many thanks for the help.
