Me and my buddy were gonna tackle changing my fork seals and putting new bushings in on my 01 YZ426 and I was wondering if anyway has done that before on this bike.

If anyone has how hard will it be to do without a manual?

How long should the job take?

Seals and bushings take me about an hour after they are off the bike.Some may do it faster some may do it slower but thats a good avg. :applause:

It's a piece of cake. Read:

http://www.thumperfa.../fork_seals.htm

I know the page is for a 250F, but the forks are the same.

Recommendations:

Buy a seal driver, or take some time and make a good one. They are absolutely worth it. Remember that you will pay a shop $120 or more for this job before you balk at spending the money/time.

Check for nicks and for vertical scratches that are large enough to feel with a fingernail. If you find them, sand them out with 250-180 grit wet/dry. Don't worry about the finish, the normal fork operation will restore that in a short while.

it really is all about the tools. If you have the fork seal drivers, the job is really simple.

Be sure to get a complete kit. you may want to try the pivot works kit with everything. if you are purchasing seperately, be sure to get new wipers also with the seals. I know ProX makes some good priced seal and wiper kits through WPS

Very good tip. I would imagine that even what appears to be a small nick or scratch could cause perfectly good seals to leaks.
