Marzocchi setup help - 08' EC250
 

Two tight woodland events has left me wanting a little more comfort from my EC's suspension, the bike handles great and goes wherever I point it, but it's a little harsh over small woops/rutted woodland, and also the front is quite unstable over bumps at speed. Looking for the first 2-3" to be a little softer before I get into the harder part on the fork? Could this be achieved by increesing the air gap or will that move the problem somewhere else?

I go about 200lb in full gear, the rear sag is correct. I asume the springs are standard. The back seams fine, but after alot of adjustmens at the weekend, I think I've run out of adjustment?

Anyone?:( .

I would recommend 130 or 140mm oil height it's an easy change to make as well.

Let us know how you get on with that.

woops sorry that's for the 05 marzocchi's.

I would still look at increasing air gap but the 130-140mm height may not be correct for your (sachs?) forks. You could look what it is now and increase it though as long as the sachs are an open oil bath type fork - not sealed cartrige like the Kayaba's.

For referance the original oil height was 90mm on the marzocchi's and a move to 130-140mm gives a plusher ride.

I think 130 - 140mm is too much for the Zokes. I'm running 110mm with 0.46 springs and I previously ran 120mm with 0.48. But there is a lot of personal preference involved. However as stay_upright may have springs that are too heavy for him that may be why he can run a big air gap.

As posted on another thread.

The factory guys told me to leave the preload alone. What they told me is to remove the bottom shim stack from each fork. Take the nut off and remove ONE of the three large shims from the stack. Keep the shim handy because you might want to put it back in once the forks have broken in. They claim it takes 20 to 30 hours before the forks fully break in (Sacks). Also you need to take out the top space an mill 4mm off of it and mill a little out of the shoulder of the cap. This gets the fork to settle down into its stroke alitte bit. To turn the preload adjuster (if you must) Just find a nut that is the correct size. I would contact Mark at GoFasters. They should have a video of all of this.

Ok, so these are my idears so far, please advise as you see fit.

1, increes oil air gap, I'll go quite low at first and top it up to get the right feel.
2, replace fork oil, the bikes about 16 months old. The manual says SWA 5-7.5? what should I use?
3, Check lower fork clamp bolts, how tight? any thred lock?

Now we get to the trickier part, after reading through some threds, i was thinking of making some shim stack adjustment, can anyone advise me on exactly what I should and should not touch? I unterstand the the forks may not have enough rebound adjustment? and I read you can remove a bleed shim to speed this up? Can anyone advise?

Should I look at the comp stack at all?

Thank for the help, just like to add the only time I've ever been inside the fork are for standard sevice resons, this is why I'm keen to get as much info as possible, not that I'm worried about doing the work, infact I find the whole subject quite intresting:) .

Ayone?:confused:

Thanks for the help:mad:

What forks have you got? They may not know if you have the Sachs forks they're very new on GG.
