It is possible to buy preload spacers for Lyriks. Am i right in thinking that these can be used to fine tune the spring rate if you are between spring weights?
not for a uturn fork
Monkeyboy, there is about 10mm of allowable preload that is available. However no such spacers exist, I have fettled may times with my lyriks and now run my 2007 160's at 170mm de-utilising the u-turn which in turn provides the required ramp up at end of stroke. It's not a pretty mod but has held up good so far , even a week in Morzine.
how do you do that?

A long story but since Rockshox have dropped the 170mm RC2DH fixed coil for 2012, they ended up specifically making one for me. They also chucked a couple of these preload spacers in the box. I haven't used them yet, but just wondering.
Hmmm, interesting that. I suspect that it is to do with the 170mm non uturn versions only though.
Cruzheckler, I have heavily modified my Lyriks as follows: -
5wt oil in compression to allow better SBC (Small bump compliance on full off HS /LS)and finer range of damping.
Floodgate mod again better SBC due to better oil flow.
Secondary oil seal removal on main stanchions, now running foam seals. Again much better SBC due to less stiction and better lubrication (Oil / grease mix).
170mm mod by removing the last part of the coil of the u-turn spring, allowing you to wind out the coil a further 10mm max (You will not need to adjust the MC oil level) You will need to fix the spring in place to prevent over turning and winding the spring out of the u-tun assembly completey. This mod also brings into play the u-turn spring area providing a higher ramp up levelat bottom out (See pic above).
kona - 5wt is stock in the damper??
done the dh mod
where did you get the foam rings from?
Cruzheckler, the origional RS spec oil came in at about 7.5wt against the standard.
I got the foam rings from TFTuned, they called it the "Boxxer" mod.

Nope, preloading a spring doesn't change the spring rate.

Aye, I was going to say that the narrower coil section at the end is more for the U-turn mechanism than for the spring rate. Will have some effect at full travel, but I suspect quite small.
Not necessarily Northwind, if the preload spring acts with the main spring without affecting the ammount of travel this will actually affect the overall spring rate at one point of the travel.
So the answer may be... yes!
Stevomcd, exactly but winding out the extra 10mm brings it into play more.
Konastoner, he's not talking about a preload spring but spacers.
Sorry to resurrect and old-(ish) thread. Can someone please explain what effect using the preload spacers (effectively thinnish penny washers) would have on the the fork. Also, how does this compare to increasing compression damping? I've only had the fork for a few weeks and am still getting used to it. At the moment, doing a 6ft drop to a flattish landing is using a [i]lot[/i] of travel.
Cheers.
