  6. Adjusting The Steering Head (Dowty Fork)

Slacken both the clamp bolts on the fork crown fitting and the pad bolt on the handlebar clip lug. Adjust steering head nut as required. Re-tighten pad bolt hard and clamp bolts on completion of adjustment.

It is important that these two clamp bolts (in the lower head fitting) are not over-tightened, as it is comparatively easy to deform the outer tubes by excessive tightening.

If the outer tubes become deformed by this over-tightening it will be appreciated that the rubber seal will not be able to hold either air or oil and deflation of the forks will follow.
