just noticed my right fork seal has started to leak ,450k on clock .Have removed boot to see whether crap had got in side and found it clean as .Anyway have given the seal the feeler guage treatment to see whether this will help.
rusty nuts if you get a chance take wheel out and push and pull forwards and back on fork at axle end to see how much movement in fork bushes. My left has a lot and always leaks but right has very little and doesn't leak, re my above comments for thoughts on matter.
Hi all, I did the above mentioned fork modification (machine and resleeve where the lower bushing sits and replace bushes ) this took out the play in forks and now the new double lip seal can seal and does . for more info read more detailed explanation in previous post.
I have a new leftover wr250 with 50mm shivers and about 25 hrs . Last week one fork was leaking pretty good. tried the 35mm film and still leaked , but AFTER the next woods ride it stopped , so I guess it was a piece of dirt , well at least i'm not alone in this situation
