MOTOCROSS ACTION MID-WEEK REPORT
TWO-STROKE SPOTLIGHT: JASON STEFFINS 2001 YAMAHA YZ125
“These things are all over. Definitely, a fun bike to ride and build. I took this one from the brink of death, back to almost new. Stripped it down to nothing. Repainted the frame original YZ Blue. My son Langston helped on this build which made it pretty special. The engine was stripped, and new bearings, seals, and gaskets. The cylinder was shot, so we sent it over to USA Chrome to make it new. Fresh suspension by 4th Dimension Suspension, and lots of polishing and cleaning. The Doma pipe looked dead, but we got it back to almost new! Miscellaneous Tusk parts are scattered around to give it a fresh look. The bike sounds beautiful now.” –Jason Steffins.

MXA MINI TEST // N2DIRT 2022 YAMAHA YZ250 FORK/SHOCK MODS
For 2022, the YZ250 got stiffer valving, a leaf-spring-enhanced mid-valve, and stiffer springs front and rear. The stock setup works great for most riders, save for those on the fringes. We asked N2Dirt to help our heavier and faster test riders (195 pounds) keep the forks from diving and get the shock to hold up higher in the rear. N2Dirt increased the fork springs to 5.0 N/mm and the shock spring to 54 N/mm and custom-valved the shim stacks for greater speeds.
VERDICT: N2Dirt isn’t the biggest name in suspension mods, but they have enough confidence to say that if you’re not satisfied with their re-valve, they will do another re-valve for free.
DIGITS: $649.00 (fork), $909.00 (shock revalve with springs)—(661) 252-0269 or www.n2dirt.com

We had MXA test rider tuner Brian Medeiros throw some of the new SKF Dual Compound fork seals on our 2022 Suzuki RM-Z250 after the stock seals wore out. We have SKF seals on a majority of our test bikes.
InnTeck USA just released the motocross industry’s first-ever dual compound fork seal kit. The SKF fork seals have all new rubber compounds and SKF’s patent pending innovative new co-molding production technology. The seals have an extended sealing capability, which increases durability and improves riding comfort and compliance by minimizing the friction between the seals and the fork tube. The new open wound spring that comes on the seal is dedicated to applying constant force to the seal which keeps debris out of the coils and won’t dislodge during pressure washing.

ASK THE MXPERTS: BLOWN OUT IN THREADSVILLE
Please find the attached photo of the shock body from my 2011 Yamaha YZ450F. As you can see, the preload ring threads have been ruined. I’m at a loss to know exactly what happened. My local shop couldn’t give me an answer, and it cost me $1000 to buy a new shock. Obviously, I don’t want this to happen again. Would I be able to install a machined spacer over the damaged threads on the shock body, get a new preload and locking ring and salvage the old unit?
It is obvious to us that the preload ring’s threads seized on the aluminum shock body because you hit the aluminum preload ring adjuster too hard with a hammer and a punch. When you try to spin a seized preload ring by hitting it harder and harder, you run the risk of deforming the ring‚ which makes it seize even more. In the future, if the preload ring doesn’t want to spin, clean it, lube it and be gentle with it. Move it back and forth in small increments in the same way you get a truck out of mud.
Yes, you could use a spacer over the damaged threads and install a new preload ring, but there must be enough threads left to have 10mm of preload on the spring for the desired sag setting.

MOTO TIP OF THE WEEK // ARE YOUR CALLUSES TOO BIG?
MOTO TIP: Maybe you already have the manly, callused hands of a serious rider but still have issues with blisters. Chances are you’re just not taking proper care of your calluses. Calluses can get too big. When this happens, the edge of the callus forms a hot spot that creates a new blister next to the old callus. This can lead to the callus being ripped off. Not good. Use a pumice stone or callus shaver to remove excess layers of dead skin to minimize hot spots. Moisturizing rough hands at night will minimize cracking and potential hot spots.
