If I had a manual, I'd look it up. I bought the bike used and there is no manual, so I'm trying to identify the screw that adjusts the headlight. Can someone discribe where the adjustment screw is located relevant to the bulb? Above, below, to the right, . . . etc.? I understand I should be able to see it if I turn the handle bars to the left. Oh yea, I have a 2008 R2, so that may matter.
