hi,i recently bought a wr450 and whilst giving it a good check over when i got it home i discovered a fork seal was leaking quite badly.after a look around on the net i found the "seal mate" its basically a thin piece of plastic used for cleaning dirt from under the seals which the makers reckon is the problem with nine out of ten dirtbike fork seals.just do a search for seal mate on ebay and the advert contains an instructional video on how to use it and shows the results.i was a little sceptical myself but thought for less than a fiver delivered it wasnt much to lose.anway i can confirm it works,so it saved me money and an evening in a cold garage so im well pleased with it,and even people who arn"t very mechanically minded can now repair thier own fork seals.i think im supposed to add that i have no affiliation or personal interests with the company or product,just hope it helps a few people save time and money
