Valving Logic 8-23-24 Valving Logic Level 3 full access is now available for $150 per month.  Drop in, poke around and see what you can find.  Follow along on projects in real time as we run through the paces. Current project:  Revalve, respring and lower a 2023 SE F 125 Sherco for 97 lb XC rider.  Valving Logic has been around for about 20 years . . .   I remember the day.  I just got so tired of standing there guessing at what shims to change.  So we bought a dyno.  There was a big learning curve and it took about a year to get comfortable.  We quickly learned it was a big investment in time, but well worth it.  Someone got the idea, why not spread the cost around.  Others might want to get in on it and be willing chip in.   Here's what we came up with back then. The suspension tuning field is full of myths, misconceptions and guess work.  Valve stacks are twisted and tweaked, but no one ever shares what they have done or why. Valving Logic is working to change that. The concept is as simple as 1-2-3. Use the latest technologies to evaluate suspension performance and catalogue this information in a database. Eliminate as much guesswork as possible and replace it with detailed and quantifiable dyno data. Make this information available to anyone interested (for a small fee). Level 1 - basic info - free Level 2 - intermediate info - fee based Level 3 - advanced info - fee based Time advanced and things were going well, but it still felt like something was missing.  So pressure testing was added in 2013.  That was an eye opener, but a big investment in time.  While seeking to maintaining the Valving Logic free section we moved away from the original idea of levels and focused on detailed dyno and pressure testing.  Here is one of the many advantages.  Pressure testing allows you to break down the compression forces into their four main parts. FORK force from the bv piston force from the mv drag force gas force SHOCK force from main piston force from cadj drag force gas force Valving Logic evolved over the years as we incorporated new ways to document, compare and analyze the test data.  New ideas and concepts have been explored such as chassis and leverage ratio analysis.   For example, we directly link dyno and pressure data with the bikes leverage ratio for a better understanding of the applied compression and rebound forces.  This technique will be used in our current project while lowering, respringing and revalving the 2023 SE F 125 for 97 lb rider. . . . So, there you have it.  We're back full circle and putting everything out there again.  There is a bigger learning curve for anyone interested in getting back in.  20 years ago, it was learn as you go.  When something new was discovered, everybody knew about it.  But now there's this accumulation of insights and knowledge and it will take some time to get up to speed.  But, what else is there to do? Currently there is no user guide on navigating the site or on how to analyze and interpret the data.  We're working on that.  We'll be available to answer questions, but time is always limited.  Could always start a discussion on one of the suspension forums to hash things out. For those interested, there's a good bit of information and a lot to be had. [Email if interested] Disclaimers: I don't know what I'm talking about.
