Fork seals leaking @19,000 miles on ODO

Hey Frulk,

Before you go replacing the seals I'd strongly recommend trying something like the Motion-Pro Sealmate. Leaking is often caused by dust and dirt getting into the seal. The Sealmate is a thin but rigid piece of plastic that you insert between the fork seal and the fork tube. You slide it all the way around and the hook shape at the end helps pull out the grit.

A few years ago I did a lot of dirt roads on my CB11 and both forks started leaking (around 21K miles). 15 min. with the Sealmate and they haven't leaked a drop since. Same thing happened with the left seal on my CB750. I'd already replaced the seals a few years earlier, so I suspected the cause was just dirt. Sure enough, the Sealmate did the trick again.

If your seals are truly cracked, it's not going to help, but I've found that most leaking seals are just dirty. Definitely worth the small price to find out. I've actually made my own version out of plastic playing cards, using the original Sealmate as a pattern.

Dig out a old 35mm negative film strip and use that to dislodge the debris.
