In motocross circles in the 80's and early nineties which is when I had a passing involvement in this there was a drive to have the softest springs you dare, I think people always make the mistake of going too stiff.

STW Engineers - anyone know anything about oil/viscocity etc etc? (Forks)

Is this a ploy to drag me back onto the thread?
toys19 has naff all to do with me, though I did race then, but certainly never heard of that one.
Its always been about setting sag, and if you cant acheive that with the std spring then you need a different one. No rocket science in it.
Here is a true story about suspension and all the guff that can be associated with it.
I remeber a day probably about 82-3 when Aragosta shocks were becoming quite popular and their was a small crowd all boinging an RM up and down in the paddock and saying the age old things like plush, smooth, progressive bla blah blah, we was parked quite close by and my dad said OH thats nothing you want to try our bike we had a blacksmith temper the spring for us, next thing you know we got the same crowed OOHING and AHHING over a bog stock but well setup standard shock

Improve them on fast successive hits/stop them being overwhelmed.
Thats what PUSH does for a Pike.Whether its worth it to you, well, stick some Tesco Sunflower Oil in and see how you go. Got to be Tesco though, ASDA stuff breaks down to fast and the Morrisons stuff is inconsistant.

Come on Tinsy tell the truth, we are lovers... Or are you denying me?

denied.. your spelling is better and you use upper case and punctuation in the right place, I dont know anyone like that!!!

As a bogo-standard rider with no special skill or talent if cheaper fettling can get me similar results I'd rather go down that route.
If the PUSHd system would actually make me think 'WOW'! these are better than any Fox's'..then I would buy into £170 additional cost.
I was recommended the xfirm spring- its too stiff. Back a weight.

Thats what you call a free-thinking mind that is willing to think laterally

Hora, you didn't answer my question regarding sag when standing...

Yes, but only on the rebound damper, adjustment on the LSC&floodgate is used to tune this on the compression stroke.
BTW Olive oil works better than sunflower

This is the ride when it came to a head. That (tbh) is probably the most travel I got out of these forks ( they finally hydro lockedout):

(thanks to nbt for the picture).
When they are back fully working to me- spring swapped and sag set. Sorted. Then I'll take it from there.

One thing I noticed with my Pikes was that the standard spring sagged about right for me at 15.5 stone, and was actually usable on most trails, but gave it's travel too easily otherwise. Technically I should have had an X-firm I suppose, but I already knew RS spring weights are a bit pessemistic and bought a firm. That, to my mind, didn't really give enough sag, but felt bang on when riding. TBH I wish RS would give the option of U-turn or preload on their springs, it would make tuning them a lot more accurate.
I thought mine were pretty much spot on, even giving them a pasing in Morzine they were OK. You do get a bit of spiking on repeated hits, but it doesn't detract from the ride for me. I only really notice the difference when I swap bikes and ride my Vanillas. Which are undoubtedly better damped. There's not much in it, IMO, but it is there.My ideal fork - A 150mm Pike with U-turn, preload, Fox damping, Magura colours and double arch, with the longevity of an older Marzocchi. That said, RS are worth it on price and for the Maxle alone. Maxle is a thing of genius, IMO

When were the forks last serviced...lowers and damping oil?
Posted 2 years ago # -
stuartanicholson- the forks were <1 month old at that point.
I'd be using Lyriks are my first choice as they felt so bloody awful.

that all the travel you got all day in that pic? if so dont go any firmer on the spring...
Posted 2 years ago # -
Hora, I'm assuming you've had a good faff with the rebound damping?

Yep. There was no sweet spot. Anyway threads labouring abit. They should comeback repaired and will be de-springed shortly... does ton want to buy an extra-firm spring?

What length stem is that out of interest?
Seeing as x-firms seem to be almost universally dismissed as 'too firm' by people 15kg+ heavier than me I'm thinking that I might be too far over the front.

So did we determine whether the fork is packing down (massive rebound damping) or locking up (massive compression damping)? Assuming its the first just get a lighter weight oil, the oil needs to be either a fork oil or an engine oil with anti-foaming content (many engine oils have this as standard). I can't think of any other fluids I'd want in my forks. Fork oil is as cheap as chips, like £3 a litre at bike shops and available in a range of weights (you can even mix your own!) and is chemically designed for the task, why would you think putting veg oil in it would make more sense than an oil designed for the task? That's like thinking that sticking two sticks of bamboo up front would work better than your pikes because the designers must have felt an overwhelming need to use metal instead of the clearly better bamboo.

If its on the 456 - 70mm Thomson.
coffeeking- it was an open question on viscosity of oil etc.

Ok they are back from Fisher- Hydraulocked and rebound cart replaced.
Im not going to bother with fettling/fine tuning them (as above) as Ive already bought a new set of Lyriks.

Hora, i'm suprised it took so long. If you need help setting up Lyriks some good info can be found here: -

Thanks for that but I bought 2-step air Lyriks!

Following the descent to Edale from Jacobs Ladder this week, yes I do need it. I could barely hold onto the bars (think trying to shake themselves silly out of my admittably strong hands/grip).
Why do I break forks? Seriously. I'm SHIT at riding but always seem to find the particular forks Nemesis.
