The only thing i can believe is that, because of on the spring there is no code, the suspensionist has made a big big mistake

The unnecessary spring length of 190 mm would indicate this. Is there additional preload on that heavy spring?

i was riding with about 20mm of preload.

Original, stock red spring was same 190mm length.

The stock spring is still compressed with the preload rings topping out. This would be the furthest you can reduce preload just to give it a try. And as stated play with a reduction of compression damping as well. Such a stiff spring will need considerably less support from damping, as it simply can´t wallow through the limited stroke as the weak stock spring does in this case.

i already packed the shock to get back to suspensionist
i paid (a lot of) money to have the shock serviced and with correct spring Laughing
so i dont want to drive a wood board instead of a bike anymore Laughing

at this point i'm pretty sure that the spring is wrong.

I understand: After spending big bucks you have the right to get things sorted out properly. I hope you don´t lose the best part of the riding season waiting for the (hopefully perfectly sorted out) shock!

Please leave feedback once you got the shock back and had a chance to test-ride it!

i hope not!
Last time he was very quick.

Anyway in this period riding the bike here is not so good: it's very, very hot.
Also the bike does not like this weather so much....i felt some engine head knock with these temperatures.

But for sure i want the bike perfectly running when in august i have some holydays [You must be registered and logged in to see this image.]

Moto, the company repairing your shock is doing a full rebuild on the shock (seals, oil, gas...)?
The guy who rebuild mine had to install a Schraeder valve to fill it with gas in the end (you can see it in the picture of my schock). He said the shock doesn't have it because at Sachs the shock is closed in a pressurizer chamber.

yep, shock was full rebuilt

usually stock shocks haven't the valve that will be installed at 1st rebuild.

It's the same, for example, with the mayority of kyb/showa shocks of japanese bikes.

Found a picture of a 110N/mm spring with 57ID on the web

Except for my 28 years old DR 650, that had a KYB shock with a shrader valve in stock form. This is great if you refill the air chamber using a shock-pump from a fullsuspension MTB after replacing the oil. In fact, new shock oil every few years is not a big deal to DIY and keeps your shock well lubricated and functioning for literally forever. That is if you not only replace the oil but get rid of the dark sludge that built up inside first.

1. drain air pressure
2. unmount spring
3. remove the cap with the compression adjuster from reservoir
4. drain oil by pumping the shock
5. fill shock with solvent and pump out junk
6. remove solvent and let shock dry
7. refill with oil
8. bleed oil circuit by pumping until no more bubbles rise
9. overfill shock and reinstall compression adjuster cap
10. reinstall spring, pump to 11 bar

what kind of solvent do you use to clean up the inner chamber of the shock?
Years ago i used to clean my fork internal simply using cheap fork oil.

You could use fork oil, gasoline, in fact anything petrol-based. No need to go hyper-aggressive as the main goal is to remove sediments of metal shavings and dirt.

Thank you. Next time i'll try with gasoline.

Anyway, my shock is coming home. The suspensionist told me that has swapped the spring (he said that previous one was 115N/mm...but i m still not sure) and installed a 100N/mm.
He also changed the internal hydraulic setting.
We'll see if now the bike starts to handle properly Laughing

Once the Hyperpro is added, definitely get a proper setup for sag & rebound by someone who knows what they are doing with you on the bike in full gear to simulate the weight.

Once I had that done on the GRiSO, the bike handles like a charm...no wallowing, no double dipping, firm and soaks up the bumps in the corners just like the Norge and Scura.

Night & day difference having the spring / sag / rebound done.

Best of luck!

Hi all,
After a ridiculous time waiting for the swingarm bearings (involving receiving incorrect parts, claim them and order again), I have finally the bike in one piece again bounce
The works included:
- Hyperpro spring + shock rebuild
- New suspension conrod link
- New swinarm bearings
I finalized the assembly today.
Tomorrow I plan to adjust the sag and take it for a test ride bounce bounce bounce

I have currently the compression at 1,5 turns out, and the rebound at 25 clicks out.
But the rebound seems to be too slow (when pusing the tail down the recovery - specially the final part- seems slooo[You must be registered and logged in to see this link.]
Maybe i will try the 39 clicks out like you have Capitan...

Ok got the shock back.
The new spring is 160mm length, they told me that is 100Nm/mm.
I think it's the perfect length for (future) installation of an hydraulic preloader from norge/stelvio, but using it with standard preload rings seems to be too less range of preload, 15mm with rings at the end of the threads.
I'll made and aluminium spacer to get more range before install it on the bike, to get a range between 0 and 30 mm of preload.
Anyone can suggest a baseline preload to start with?

The Hyperpro has 170mm in free condition. I don't know the rate values, but it is a progressive rate spring, meaning the rate increases as the spring is compressed.
They recommend, for the GRiSO, a preload compression of 10-15mm. I'm setting up the sag today, and i believe I will stay close to the 15mm (I weight 90kg).

I just came back from my first ride. These were the settings:
- Spring preload compression: ~15 mm (rider sag: ~28mm)
- Compression: 1+3/4 out
- Rebound: 27 out

Noticeable increase in confort, but mostly on the handling...I don't know out much comes out from the spring and from the new bearings...

Still need to test the dual ride, once this was the main issue.

great.
What about your rear static sag?

I made the spacer, next week i'll rebuild the bike, now i can adjust from 0 to 30mm of preload.

The spacer is a good idea....In my case I believe I have enough adjustment, but very tight....

me not, as i said before, this is a good thing because if tomorrow i want to install hydraulic preloader i have not to change the spring again
I think that in my case a minimum of 15-20mm preload is necessary to get a correct sag
