Question about servicing forks

[hashtag_g]

I noticed that the forks on my 81 xs400 were sagging and not rebounding to a consistent height when compressed so I disassembled them and drained the oil with the help of this youtube tutorial (very detailed).

If I replace the fork seals and change the fork oil will this solve the problem? Everything else looks to be in okay shape. Are their signs of wear that aren't obvious I should look for?

Thanks for your help, I can post pictures in a few hours when I get home if anyone is curious.

Probably not unfortunately. The forks on these bikes aren't the greatest. If you do a bit of searching, you'll see a lot of complaints about them. My forks have a whopping 2000 miles on them and still experience the same problems you mentioned. That's why I made the switch to modern forks.

Ouch, did you do the RS125 conversion? I'm having trouble finding where people are getting the RS parts.

I have all the RS125 parts, just need to put them on.

I grabbed my parts from the UK. Very plentiful over there. Shipping wasn't as bad as you'd think.

On such a simple fork I would just run them as is or swap for something newer.

My fork springs measured about 4mm short of spec so I bought Progressive Suspension replacements (11-1115) as recommended on other threads. Hopefully this will do the trick!
