I have a 2022 hypermotard SP I've been thinking of re valving I don't ride the track I just simply don't have time for that i-ride Street, and this bike is Harsh as hell on these bumpy roads. So when I first set up the suspension of course I set the SAG and I turned everything out completely to 0 and then slowly started to turn things up. I think I've got it about as good as it gets right now. It does okay at low speed but if I get up about 80 miles an hour on some of these roads it feels like I'm running over parking curbs.

I’ve learned so much about these shocks watching your vids. Thanks! I rebuilt an old Noleen mountain bike shock and hand bled it carefully. Even with a new seal head rebuild, I found I’m getting a bit of weepage/leakage where the shaft meets the body. Should I rebuild it again or is it possible I filled with too much oil and there is an initial purge? .... I know, hopeful thinking.

Sometimes when hand bleeding oil just gets pooled on top of the seal head. Might be nothing. Once the gas in in see if there is any play in the shaft. If not you are probably OK. Thanks for watching!

Hi Ali. Best way to stiffen if you don't have any adjustment is to revalve. Let me know what you mean by monotube or inverted. Monotube shocks with a nitrogen reservoir and separator piston (not an emulsion shock) are great if they are valved correctly. They can be inverted

What software do you use for shim stack design?
@theohlinsguy46498 ай бұрын
Hi. I don't really use any software. I just kind of know what I want to see and mess with it until I get it where I like it. I just have lots of experience but still need to mess with it to get what I want. I have a dyno to see what I have done. I have lots of data stored on my dyno so I kind of know what I have done before to get what I want and I have a starting point. There is no software that tells you what is better or worse that I know of and if you can find one it will be bogus. There is software for Ohlins TTX40s that you can also use with some success on TTX36. Look up Ohlins Valve Referencing Program (VRP). There are a bunch of different shim stacks in the program and last time I looked two valve choices. (linear and digressive) It can get you in the ballpark of where you want to be. I never use two way adjusters (low and high speed) so if you are using single adjustment you can just put the High Speed at about 38 and it usually is close to correct when manipulating the low speed adjustment. Remember that this software just tells you what the damping might look like but not what is better or worse.

Nowhere on the internet you can find videos about the development of the (motocross) Ohlins shock absorbers over the last 30 years. Yet THAT would be a particularly interesting topic that would lead to an understanding of the many iterations in constant development. If you compare two shock absorbers in principle (Kawasaki KX500 / 1988 and Kawasaki KXF450 / 2024 - as an example) - what fundamental differences cause the massive progress? Are there big differences in the lever systems? What do the shock absorber pistons look like in direct comparison? How do the control mechanisms work? How do the filling quantities or the oil used differ? How have the shim stacks changed - and why? THAT would be really interesting to hear from an expert!
@theohlinsguy46492 ай бұрын
I am not an expert, just a tech. I am a car racer. I don't know much about motocross almost never do any newer motocross shocks. My mentor, the late Bruce Burness, was on the forefront of this technology in the 70's at the beginning of Ohlins. He was DeCoster's guy for the last two championships and did shocks for motocross champions through the 70's. I am not sure that the shock and forks do the same job with the newer bikes in that so things might be different now with longer travels and a lot of air time. Another problem is that the real guys in the big teams, as in all racing, aren't really giving out the information on what they are doing so a lot of the stuff on the internet comes from "experts" who don't know what they don't know. I wish I could be more help to you but I don't want to be one of those guys with white boards telling people stuff I really don't know about. I am kind of out of stuff I know about.

@@theohlinsguy4649 Thank you for your quick reply! You mentioned that you don't consider yourself an expert. I don't agree with that - and I would like to thank you very much for your videos on KZbin - which provide a lot of important understanding of vehicle suspension. My question in relation to the further development of shock absorbers on motocross motorcycles (but not only there) and a comparison between the mid-80s and today has to do with the fact that even back then the basic development of the lever systems, the length of the spring travel and the chassis geometry itself were very similar (about 95% of the 2024 status) compared to today - but the shock absorbers / front forks certainly weren't. This certainly also applies to the elements for road racing motorcycles in the Superbike and MotoGP competitions. During the 80’s I was involved in the development of chassis- and suspension-systems for teams in the Motocross World Championship (Kawasaki / Yamaha) - so I'm naturally interested in how the problems from back then were solved. This means fundamental changes, not individual adjustments. BR

@@move-it-777 Dampers are there to stop oscillation. The smoother the tire patch is to the ground the more grip. When you start using them for other things it is a slippery slope. My beliefs are: Linear damping with the most compression and the least rebound (usually both are the same value) and the least amount of total damping possible. Rebound is the enemy of grip. In cars, if aero is more important than grip, you might want to use the damper to keep the aero in optimal position rather than worrying about grip. With motocross I don't know what factors are more important. If it is mechanical grip I think these rules still apply. If you have un-linear linkages this probably would be hard to do. Just my opinion

@theohlinsguy46494 жыл бұрын
Hi Tuan Current racing shocks invariably have an oil reservoir that has a floating separator piston inside and is highly pressurized with nitrogen on the far side of the floating piston. This is necessary to always keep clear oil around the shaft piston. The reservoir has another function which is to accommodate some oil that moves to the reservoir when the shaft is moved into the shock body. As the shock is compressed the shaft and the main piston passes through the oil. Most of the oil moves from one side of the piston to the other. Below the piston it is solid oil. Above the piston there is solid oil and an incoming shaft. All the oil below the piston can’t pass through to the other side of the piston because the shaft is taking up some of the available volume. In addition the shaft takes up more and more volume as it enters the shock. Where does that extra oil go? It goes to the reservoir. To take advantage of this displaced oil, there are some more circuits at the entry to the reservoir that can be used to fine tune the compression damping curves. The reservoir generally has a bleed orifice with an adjustable needle (two-way) and sometimes a device to preload the miniature shims (three-way). Because there is a much smaller amount of oil traveling to the reservoir compared to the oil that crosses the main piston, it is not a good idea to use the reservoir and/or canister for anything other than small adjustments to the compression damping. However, this is still very useful at the racetrack. There are a couple of potential problems with making too much damping at the reservoir. Depending on the particular shock dimensions, the oil that travels to the reservoir is around 12% of the oil that travels across the main piton. If your shock has a reservoir, the total compression damping is the sum of the damping created at the main piston plus the damping from the reservoir. To keep all the shock oil at the same level of stress, don’t attempt to crate more than 12% of the damping curve at the reservoir. A disproportionate amount of reservoir damping will raise the overall oil pressure, which will increase the hysteresis in the oil. I hope this helps. Thanks for watching and commenting!
