I'm surprised a search didn't turn up anything, but the problem I'm having now is that my bike's headlights are WAY too high.
Did I say W-A-Y too high?
Like, when I flash the high beam I can see it lighting up the tree tops ahead of me.

Now, the manual says the adjustment is to be left to the service personnel.
Is this so?

In case it is, should I worry that they're going to do irreversible damage to the bike that may cause vibrations or other inconveniences? (like breaking silicone seals, glued stuff, whatever)
My bike is new and I'll live with the unusable high beam if that means keeping it from getting any weird noises or vibrations.

Thanks in advance!
