Amazing, great master content! About the shims changing, what is the difference between then? Size, thickness? Waiting for morotcycle services. Thanks for share!
Hi Douglas Shims come in different diameters and thicknesses. Shims for the single tube Ohlins also are available with notches and there are ring shims which are used to add preload to shim stacks. Valving involves arranging shims to get the damping to look like you want it to. I will do a video or two one pistons and shims soon. Some brands of shocks have a limited selection of shims so it makes it hard to get the damping you want. Thanks for watching my channel!!
Hi Tim. There is no use I can see for digressive damping if you are trying to valve for any application where you are trying to get mechanical grip. The two reasons I hear (and believe are bogus) are (1) because it helps the vehicle get over bumps and curbs or (2) to "hold up the platform" on turn in. The first one is untrue and the second one might work for that but it is not the job of the damping and compromises mechanical grip. Let me know what you are being told about the use of digressive damping and I will be happy to give you my opinion or tell you what I know. Thanks for the comment!!
@@theohlinsguy4649 I'd imagine digressive valving (blow-off) could potentially lose stability and predictability depending on where the knee (blow-off) is in the curve.
@@oinojo Hi Jonathan. Sorry it took me so long to respond. For some reason I didn't see your comment until now. I think blow-off is digressive but is different from building digressive damping in valving. My definition of blow off is where there is a separate circuit that opens at a given high velocity. That being said you are very correct that they are essentially the same thing and your contention that it causes a loss of stability and predictability would, in my opinion, be correct. A lot of Ohlins shocks designed for rally etc. have adjustable hydraulic stops at the end of the stroke that are the opposite of digressive. It always seemed to me that digressing the damping at higher velocities was the wrong thing to do. Again, just my opinion. If the valving is correct and linear it automatically takes care of most big hits or bumps. I believe that if your vehicle is getting knocked around over bumps it is because you are overdamped, especially at low velocities.
I don't believe revalving is necessary when you make a spring change. Is this a bike you bought that is sprung for a much heavier rider? What is the year make and model of the bike? Do you know if the Ohlins shock was OEM or aftermarket?
@@theohlinsguy4649 it’s a shock that I got that is sprung for a 250lb rider and I’m 180lb and was told by a guy would need revalve done wasn’t sure why so I figured I price it out but if all I need is spring then that’s cool

what is the name of the device to insert or release the wind in the tube?
Hi Dhonlee It is a "Gas Fill Device Assembly". It comes in a kit form Ohlins. Ohlins Part# 01781-01. Thanks for watching!!
Hello,
Did I hear correct?
You are using #150 sandpaper for scratching the valve surface?
Yes, with a bit of oil.
@@theohlinsguy4649 thank you for the answer !
Where would you use digressive over linear?

How much would it cost to revalve and change spring for a 180lb rider on a motorcycle ohlin rear shock

@@truckerlyfe5319 The spring that is specified by Ohlins for your weight is 110nm.

Need louder sound with mini microphone please....my tks..
Thanks! I finally just use the mic on my camera. Seems better. It's a process!
Your tutorials are amazing but please don't attach that looooong history of yours
