the other day, in the dark..I noticed my headlight was pointing very high and the adjuster had no effect. So, today I looked at it....it was hard to see and hard to see what was wrong. So, I backed the adjusting knob off...until it "popped" I guess I broke something. I'm feeling particularly inept today...would one of y'all guide me in this a little? I know...it's such a little thing. If I can't deal with this what the hell am I doing with this complicated of a bike. Just humor me please. It's an off day.
