Subject: Rear shock access question Mon Mar 07, 2022 2:56 am
I need to play around with spring rates on my Stelvio shock 11 Kg/mm is too low so i want to try 12 Kg/mm and then as the preload adjuster is broken i want to try various spacers under the spring to set ride height.
So what is the easiest way to get the shock in and out??
so far i have used the 'remove: pork chops, wheel, bevel box, suspension links & swing arm route' is there an easier way?

I removed the right pork chop to get to the top bolt and the left pork chop to remove the stock unit and insert the Stelvio unit. Apart from undoing the bottom linkages, that was all I needed to undo/remove.

Defo not from above (I've done both) due to potential to damage wiring & air inlet rubber bits. I remove rear wheel to allow more movement of swing arm, exhaust and probably the LHS porkchop but only loosen it if I remember right. Would never remove bevel box for this job.
I would remove the pre load adjuster, its a unit. Looks to be mechanical not hydraulic. Probably an offset cog arrangment maybe. Strip it see if its serviceable. if its doing nothing why not.
Am 107kilos 17stone, I moved my rear shock 2inches total sag and adjusted about just under a centimeter to get it to 1'' 1/2 of sag. If you bought same spring it is likely as you weigh less it might well be spot on with no adjustments or spacers.
This is one I bought from demon tweaks £37 delivered. (12.5kg/mm) Exact one I've listed in the picture. They leave out the last bit but you can verify on faulkners website as I did or check picture below, dont buy from them though as works out much more expensive as their shipping is massive.

The preload adjuster is hydraulic, the oil filler is the sacred behind the adjuster block. Unfortunately mine leaks all the oil straightaway. Haven't found any spare

Oh well least you tried, no seal you can replace? Was the shock spring info any use? Thats how much I loaded it up to get the extra inch of sag off. In the picture it shows some spring centralisation spacer things, one of them suit me if spring pre load adjuster failed. No mention of them or listed that I can find.

A bit sadly i got my spring from Faulkners not realising DT was so much cheaper.
Didn't really understand your sag figures, i had fractions of inches 'beaten' out of me in the 1970s when i worked as a motorcycle mechanic (on Triumphs!!)
I am aiming for 10mm bike-only-sag and 35- 40mm with-rider-sag. Starting with a 3mm preload spacer.

Yea I hit faulkners as seemed cheaper until seen postage, they is engineers without demon tweaks postal clout.
Paulbrice taught me about the shocks, the rest I scraped together from the ghetto over matris shocks. Think you mentioned the puny springs on the older non NTX shocks. 35mm - 37.5 if want to be pedantic max sag with rider is what you want thats 1'' 1/2 on the rear. I wouldnt worry about what the bike is doing when your not on it.
I am 106Kg in riding gear and a 12 Kg/mm spring on the Stelvio shock is spot on.
The 11 Kg/mm was too soft for my weight but if there are any slim people on GRiSO in UK make me an offer.
@Buellbloke - where did you get those spring centralisation washers

You fat bastard just shy of my weight Actually am tall with a pot belly not really fat just a big c*nt Um you lost me what spring centralisation washers?, there's pictures of them on demon tweaks website I thought you could use as spacers for your 11kg spring. Otherwise spring goes straight on in place of original. Personally think bike rides like it did, just not that harsh bottoming out ride, still on the firm side.
