R1150GS high beam adjustment

[Tallmarkb59]

Just bought a used R1150Gs, year 2000, and the high beam is aimed somewhere around the centre of the low beam area! My Haynes manual shows two adjuster screws for left / right and up / down, but does not say which is which.
So, which screw adjusts up / down please, the lower screw or the upper screw?
Thanks.

Why not park it in front of a wall, put the beam on and adjust one of the screws. If it isnt that one, its the other one.

I thought you would be able to work it out for yourself. When viewed from the front of the bike. The screws are positioned diagonally across the light so the top left screw will move the light left and right and up and down. Likewise the bottom right screw will do the same.

The high beam is hinged at the fixed point which is top right when viewed from the front facing the light

Facing the light to make adjustments
Top left screw and bottom right screw clockwise = light moves down and left (right if viewed from rider position)
Top left screw clockwise = light moves left
Top left screw clockwise bottom right screw anti clockwise = light moves up and to the left
Bottom right screw anti-clockwise = light moves up
Top left screw anti clockwise and bottom right screw anti clockwise = light moves up and right
Top left screw anti-clockwise = light moves right
Top left screw anti clockwise bottom right screw clockwise = light moves down and right
Bottom right screw clockwise = light moves down.

You need to move each screw the same amount to get the direction of travel, whether clockwise or anti clockwise.

Good luck
Ian

I am happy with the left / right adjustment and don't want to upset it. Past experience has shown that the suck it and see method means more work in the end.
But thanks, Ian. I'll have a go.

This should help.

If i may chime in with my question on this topic. My low beam, when throw on a wall gives an obtuse angle of about 150 - 160degree but it's a tilted 'V'. To be clearer, it's not a perfectly aligned V, but tilts to the left. My initial suspect was the lens but maybe one of screws/knobs controls it. Anyone have an idea on this?

Thanks for the diagram, much appreciated.

What position is the big lever in on the back of the headlight? Up or down?

Read #5. Move swivel lever to horizontal position(basic setting).

Check that when viewed from the front that the lens is square to the ground. If it's at an angle then it could be set for left hand drive roads.

The low beam unit twists through about 10 degrees so that the light pattern can be set for left hand drive and right hand drive.

If you need to adjust it, then remove the front silver cover, you will see a Allan head screw towards the front of the low been unit. Loosening the screw will release the clamp and allow the light unit to twist to either of the the two stops.

Once you have positioned the light unit to the correct position, tighten the clamp and refit the silver cover.

Thank you for the leads. I'll also check it against GSA to see if similar thing occurs.

Don't look at the diagram light pattern, that's a USA style beam pattern. Euro headlights are a V angle and should kick up on the left for UK with a flat beam on the right. When you rotate the low beam for use abroad it kicks up on the right. Your light sounds perfectly normal.

This can be confusing. Despite everything you said being correct, BMW do produce a LHD and a RHD headlight for the 1150. If it is LHD then the rectangle in the lens will be 'straight' when the 'kick-up' is to the right; if it is a RHD one the rectangle will be straight when it kicks up to the left.

This came up a few years back when a member here had bought an imported bike without knowing it...

Further to Mike O' comments, I can confirm this. When I registered my 1150 in Austria they would not accept my headlight because the dipped beam was incorrect. Turning the unit did not meet the standard. I had to fit a LHD dipped beam unit. In Austria the test prior to registration has to be done by an official dealer and is much more rigorous than our own MOT test. I soon discovered that subsequent Austrian MOT equivalent test carried out at our local garage were slightly more relaxed!
