How to tune Valves & Shim Stacks | Offroad Engineered

[@topstar3]

I must have watched this video 30 times already. You sir, are amazing at explaining this stuff. Your animations are amazing, you speak slowly and concisely and pause so that the information can "stick" in my brain. THANK YOU for your work on this topic! I was able to revalve my own suspension and the results were amazing!

[@StepstoPodium]

Thank you so much for the amazing feedback!!! 🙌🙌🙌 that is exactly the goal of these videos, to help the average joe understand what has been considered too complex to do 💪 you sir, just made my week!

Im 56 and have done my own suspension last 40 years. This video is by far the best one I have ever seen. I knew only 50% of what you show. Excellent done 👍🏼🙏.

[@StepstoPodium]

Thank you!! Im glad I can help you with that! 😄🙌

The animations (and the graph) showing what you're saying and the exact expected change is just second to none

[@jamesjobe927]

This is exactly what I needed! I once dreamed of working in the suspension industry but was met with gatekeepers and old salts who bragged about how great they were but wouldn’t share. It totally turned me off of it. They lost a capable successor to their business. Now I work in a different industry and am happy to share with others just like you have here. Cheers!

[@mxtuner3351]

I Have to hand it to you. I've been doing suspension for going on 30 years. I've never seen an explanation so clear and (this is what I find extremely rare) accurate information. And your point about changing the shims is the easy part. Knowing which shims to change to accomplish what a rider needs is the hard part that only experience with different suspensions and different riders will take decades to learn. Great diagrams got your point across perfectly. Very good job, guys!

[@StepstoPodium]

Thank you so much 🙏🙌 I really appreciate it, specially coming from an experienced tuner 😄💪true indeed, knowing what you can change is one thing, knowing which one to change is another ball game that only experience will get you 👌

[@6Twisted]

Thank you for this simple explanation. My 2022 WR450F is far too harsh for trail riding. I did a 150 mile ride last week and I was in agony for the second half and I still have shoulder pain. Having too much damping is dangerous because it leads to early fatigue which leads to more mistakes or whiskey throttle.

[@JohnVanHolt]

Thanks for providing a basic understanding of shim stacks. It makes a lot of sense now why tuners who have a lot experience are desired. The principles seem relatively simple, but the application is difficult!

[@250txc]

​ @StepstoPodium I have to admit that I finally made a change to soften my KYB 48mm forks for the better on trails \ rough terrain. *This ~miracle was accomplished heavily due to the examples towards the end of this video where you show what the slightly different shim configurations make on the overall action of the forks.*

[@StepstoPodium]

God damn man! You just made my day! 🥳 really glad to hear it and thank you very much for comming back to leave a comment 🙌🙏

[@250txc]

@@StepstoPodium My fix revolved around that cross-over shim. Out of a 12 shim only 'straight' stack, I removed 2 large shims off the top, then I placed a small cross-over shim 5 notches down on the low-speed side and then removed 1 shim from what you called the high-speed stack and got the relief that had eluded me for decade++. -- I have 4 sets of the 48mm KYBs, all on my 2008 - 2012 Husqvarna 2t and 4t dirt bikes. Might do each just a little different since I have a clue now on these stacks AND the compression valve can be removed from the forks WITHOUT taking the fork off the bike. -- Their valving just screws right out the top and the mounted forks with only the handlebars needing to be removed.

[@hachtenduro7824]

Great explanation of a complex topic. Much better than anything I found so far. Still a normal user should not think it is easy to figure out the right modification. It should be left to experts. Instead of try and error expert calculations are much more efficient. One thing is not correct. Single stage shim stacks do not create a linear relation between stroke speed and damping force. The relation is degressive, creating too little damping in large movements etc.. Two stages can linearize the relation. Or a combination of valves (basevalve single stage and midvalve with float) --> a great source for such information is the Restackor software and related documentation internet pages.

My old 96 KX250 was completely transformed with proper suspension setup

[@aaaaaaaaaaaaaaaargh]

Every bike will be better with tuning. Only few people know how to do this.

[@chrisvids1820]

@aaaaaaaaaaaaaaaargh agreed. Especially when the rider is heavier or lighter than the "standard". On my KX the stock front springs were rediculously soft. I looked them up. According to racetech, they were for a 130lb rider. Rear spring was 160lb. I ended up hiring a guy that has been doing dirtbike and sled suspension for 20 years. I told him I wanted gold valves, and he said that he could make the suspension work just as well on stock valves, and it would be cheaper. I told him to just put a GV in the rear just because. Anyways, I love riding that bike now. The suspension fixed an understeer problem, and obviously bottoming issues.
