Part 2 covers the reassembly of the fork and adding the correct measurement of oil into each fork leg. This instructional video of the rebuild of the Cartridge type fork which is commonly seen on late model dirt bikes. Replacing your leaking fork seals is easy and we'll show you how to do it!
"Wow did you see what the bikes looked like after a couple of laps on the Southwick track? They were completely covered in sand, you could hardly tell what color they were. If you ride in these type of conditions you know how important it is to really get your bike clean after a ride. Sand left on your bike acts like heavy duty sand paper (pun intended) and will rapidly wear things out. If you walked the pits at Southwick after the races you see lots of Matrix cleaning solutions being used. I have used the Formula products for years and have never been disappointed in how well they work. I have never found anything that cleans as well and leaves the bike looking new. I highly recommend the Matrix Formula Liquid Solutions. Try them you'll be amazed at how good you bike will look.

I've been using a Matrix Pit table for over a year. It helps organize all my stuff and adds style. It is durable and very easy to set up. Even my wife like this table and I have to guard it from her. Every race pit can benifit from having Matrix Products organize your moto pit.

The MX43 team has been using SKF seals for a long time and we swear by them. Hands down the best fork seal you can get. A few pennies more but they last a lot longer. Five star product!
WHAT IS IT? SKF has a reputation for building the longest-lasting and best fork seals in the motocross biz, and its latest dual-compound innovation goes a long way to enhancing that reputation.
WHAT’S IT COST? $39.99 (one seal and wiper).

WHAT STANDS OUT? Here’s a list of things that stand out with SKF’s Dual-Compound fork seals and dust wipers.
(1) Leakers. The MXA wrecking crew goes through fork seals at the rate of one a week. That may sound bad, but we have over 25 test bikes that we race constantly. The harsh realities of racing in gritty soil guarantee that at any given time one of our test bikes will have oil oozing towards the front brake rotor. A leaking fork seal means downtime, because modern upside-down forks require a modicum of know-how and tools to replace a fork seal. So, when someone releases a new-style fork seal, we are on it right away.
(2) Dual-Compound. A couple of months ago we started putting SKF Dual-Compound fork seals in every leaker that we had. That allowed us to build a fleet of MXA test bikes with SKF’s newest seal. The technology attracted us because the new seals promised superior sealing, better wiping of dirt, less fork stiction and longer life. SKF Dual-Compound fork-seal technology was developed to achieve superior sealing performance by molding two different compounds together in one fork seal.
The green compound rubber is used for the fork seal’s wipers. It is tough and durable. The red compound rubber is used against the fork tubes. It is softer, more flexible and has a newly designed sealing lip. The softer rubber can follow imperfections in the fork tube to maintain a good seal against leakage. Helping the dual-compound rubber is a metal insert that provides structural integrity, and the fork wiper has a self-cleaning, open-wind spring to increase the seal pressure of the wiper.
(3) Experience. Experience has revealed to us that Kayaba seals are most likely to leak. Showa seals are second most likely, and WP seals are the least likely. Why? Because KTM’s WP forks come stock with SKF fork seals (although not Dual-Compound seals). A fork seal lives in a dirty environment where it has to endure a very long stroke at high shaft speeds with instantaneous direction changes. When you add the side loads, contamination and migration of particles to the picture, it is amazing that any seal can live up to the demands of motocross—and most don’t.
For our long-term test, we fixed every leaking OEM seal with a replacement SKF Dual-Compound fork seal. We can’t say that we never had an SKF Dual-Compound fork seal fail, but we can say that those failures came because of rock dings to the fork leg’s chrome that tore the seal’s lip. Across the board, the Dual-Compound seals offer less stiction, superior sealing and longer life.
WHAT’S THE SQUAWK? Price. SKF fork seals cost more than most aftermarket seals, although the price does include a new dust seal. Given the cost of replacing fork seals, the price of a seal that lasts twice as long is worth it.
