My forks are leaking

Edited Date/Time 1/27/2012 9:06am
So after riding yesterday I noticed both fork legs were covered in oil & dirt. Some of this gunk was on the brake caliper so I'm glad I stopped when I did.

If I pay someone to replace the seals & change oil, what is a fair price for labor & parts?

Or is this something I can do myself? I've never taken apart forks but I'm not afraid of using my wrenches. :D My bike is a 1999 kx 250.

if youre just doing a rebuild then about $60-70 per fork. if youve never done forks before, id take them in, but thats just me. ill do engine stuff all day long. just too many parts in there for me to deal with.

It's not that hard to do them yourself plus it's a good chance to clean out the forks and inspect everything for wear. Seals should be around $25. You may need new bushings as well. There are online articles at places like off-road.com that will show you how to do it.

If I remember correctly they are the standard KYB bumper style forks. Pretty easy to replace seals and get them to stop leaking.

By replacing the seals only you wont get a chance to really clean out the shim stack (cause it is at the bottom of the fork). Suspension tuners will tell you that you really need to take the entire fork apart and give everything a good "servicing". As in ... take the base assembly out and apart. Check for bent or fatigued shims, replace as necessary. Give the base valve a good cleaning. They say that most people would be surprised at how much that helps.

Thats what [b:3o7regl5]they[/b:3o7regl5] say... and it makes sense...

If you are happy with the way they perform and looking for the cheapest way out... do it yourself. I wouldn't pay someone else to replace seals on those forks...

If you feel that you want to spend the extra cash for a complete service or revalve have a reputable tuner do them.

Also

If they have never been apart or haven't been apart for a couple years I would order the bushings along with the seals.

Have you tried the Film negative or tearoff trick yet?

Just buy a new bike. Get rid of the classic. Or keep the classic and ride a new bike.

The negative film trick work's great. As for rebuilding, Buy a manual and do it yourself. The 99's are the same as the 98's and it take's me about an hour to do both fork's. Wash the fork's first. Run the clicker's to their softest setting. Loosen the upper triple tree clamp's and break free the cap's on both fork's.(The book leave's that part out). Other than that the book tell's you exactly what to do step by step. You can do it, You're MD'er. :D

Do yourself a real big favor and replace your front brake pads.
If they got any fork fluid on them they are done...

Do NOT listen to Nomad, Your brake pad's will be fine, Unless they're worn out already. If you're real worried, Spray them down with a little brake clean.

Will I need an air wrench to loosen anything?

do yourself a bigger favor and disregard that. They're cheap, probably needed anyway, and it's not worth it to try and "salvage" them. Never let suspension fluid touch your pads. My advice if you aren't a very technical person, get it done professionally. there's lots of little mistakes you can easily make that cost big $$ if you're going ot completely disassemble suspension. A torque wrench would also be super duper handy. (and having the correct torque value for everything helps too)

No air tools needed for seals only... seal drivers would help though... you can make drivers yourself but nothing works like the real tool.

If you decide to do it yourself post here when your ready to get started. I know a bunch of people on this board have done it before.

If no one here helps then PM me and I can answer any questions. I dont check the boards as much as I used to... thats why I say PM.
