250-500cc WR250 Fork Seal Replacement

I was out riding at the local track today on my WR250 2005 and I have blown out my fork seal on the left hand side. How hard are they to fix myself and is there any special tools required?

You can try cleaning the seal groove out by cutting an old credit card and making a cleaning tool out of it. Here is the fancy version of the tool that can be made with a credit card

You can make your own oil level tool with a piece of fuel line an a big syringe from you local feed store. Than will cost you less than $10

The seal driver is nice to have and I recommend buying it but you can make your own out of a piece of plastic PVC pipe.

The seal bullet is not necessary, I use a couple wraps of electrical tape around the sharp edge and then throw it away when I'm done. You can also slip a plastic sandwich bag over the end of the tube and accomplish the same thing.

I eventually bought the special wrenches but only because I'm always helping my buddies service their forks and I enjoy having the perfect tool for the job. Once you service your forks you will gain confidence and want to service them more often because fresh oil makes them work so much sweeter.

I highly recommend using SKF seals. I bought mine at Halls and they drastically improved how my forks worked because they have a lot less stiction.

Good luck.

What sort of forks are in my bike? It's a WR250 2004-2005, they are stock I'm fairly sure.

You can identify them by the top end cap as explained in the video.

Oh Okay thanks

What brand and grade of oil would you recommend? I'm 65 kgs, don't do huge jumps but I do still jump it kinda hard.

5w Maxima racing fork oil that comes in the black bottle with the blue label.
