I'm pretty mechanically inclined but this will be a learning experience..
I have all the basic tools needed to complete most jobs. What exactly will I need to make this a pain free process?

Thanks

Fork seals, I'm guessing? You need to read the manual enough times to make sense of it. Frankly, that can take quite a while. These two posts should help:

As far as tools go, you need a 49mm octagon ring wrench to unscrew the cartridge from the top of the fork tube, a 32mm octagon wrench adapter to remove the base valve from the cartridge (not required if not changing the cartridge oil or servicing any of the damping components), a damper rod holder (which is built into some cap ring wrenches, and can be a simple piece of metal strap with a 12mm x 30mm slot cut in it), and a seal driver.

It's not a hard fork to work on at all.

Sorry I forgot to include fork seal in the description :thumbsup:

Thanks for your help! I will try to get my hands on these tools and get it done.

It's not hard to do, buy a Tusk dual chamber fork cap wrench ($20) :

A fork seal bullet ($6)


Handy, but the bag the seals come in, or a simple piece of common cellophane wrap from the kitchen works about as well for nothing.

If you are just doing seals and not touching the damper then there is no need to take the top end of the fork apart. You will only need a fork seal driver, something to hold the damper rod (I actually just used a 14mm box end wrench, or a wrench in and around that size, could have been a bit bigger), and then whatever is required on that particular year fork to get the bottom of the leg apart.

Last time I did the fork seals on my 07 yz450 it probably took me 20 minutes or less. The only thing I regret not having was a seal bullet and the inginuity to use something in its place. I ended up CAREFULLY sliding the seals down over the shoulder on the inner leg with the help of some seal friendly grease, problem free.

EDIT- fork seal driver, absolute must have.

I made my own fork seal driver out of a PVC adapter that was the diameter of a fork seal on the small end and much larger on the other end for something to grab or tap on. I split it in half and used duct tape on one end as a hinge, lol. It works, but a metal one with pins that hold the halves together works better (I have one of these as well).

True enough, I service my suspension front & back every 20 hours of ride time. I've had 1 fork seal leak on me in 89 hours of runtime, actually it's leaking now but I'm one hour of ride time away from doing a complete service so it'll wait. I won't pull a fork apart unless I'm going to change the oil in the inner chamber, should've mentioned that..

Yes, I've done that before. But I like the idea of having a thin layer of hard plastic between the seal and edge(s) of the tube. The bullet isn't a necessity, but for $6 I'll use it as opposed to a bag.
