Exup, some strange black magic?

Switch the engine off with the kill switch and it will move back to the set position.

This is probably the best way to check it when adjusting.
Engine off with kill switch adjust cables to set alignment
Start engine
let it idle for a few seconds
Switch engine off with kill switch
Check the alignment

Repeat above if necessary

If adjustment takes a while, disconnect the headlight bulbs on the American imports or post 03 model, (stops the headlight draining the battery).
