Having noticed an alarming degradation in the steering on my WR it is time to change the head bearings. It is not too bad off road but damn scary on it because it feels like someone has grabbed hold of the handlebars to stop you turning as you are trying to go round a corner.
Having done a bit of research this is a really useful link if anybody else is thinking of doing the same job
