XTZ660 headlight adjustment

[davidandmo]

My XTZ failed it's MOT (UK inspection) last week because the headlights point too high, despite having passed 3 previous annual tests with the same adjustment.

I had a look in the service manual but could only find left to right adjustment. To save me experimenting, does anyone know how to adjust the lights vertically?

Also while I am asking those with high mileage bikes (Fred?), my bike has done about 60,000km and has never had any engine work other than the usual oil/filter changes and valve clearances checked. Can anyone recommend any preventative maintenance that I should be doing or is it time to check the internals? The bike still runs great and sounds fine although there appears to be a harsher vibration at around 5k revs recently. It doesn't feel relaxed cruising above 110km, but then I suppose it has always felt a bit 'vibey' and I've never cruised above 120km/h - maybe I'm too mechanically sympathetic!

Any advice would be appreciated.

Cheers

Dave
