Springs for marzocchi 48's?

[Timber]

Anyone know what spring size is used in these forks? I prefer race tech springs so if you know the rt# that would be great. I've got a new factory edition 350 and am told it has .48 in the front but it sure feels softer than that, can someone confirm the stock rate? I feel like I'm going to need .52 to hold this thing up if stock is .48.

Spring length should be 475mm (writing this from memory).

However, IMO first check PFP setting. If it is 2 turns from fully open (std setting), then try 3.
Also check and adjust outer chamber oil level. Normal is 370ml, if you add 20-30 ml you should notice the difference.

Looking at the online manual for those forks it says standard spring rate is .44. That's what they feel like. I usually end up at .48 or .50 on every bike I ride. I'm calling bullshit that these are stock .48's.

I have a pair of race tech .50's that I never used, let me know if you are interested in them for $75

also my bike came with .44 (2014 300 Racing edition)

Pm sent. Thanks.

I'm betting these forks have .44 in them regardless of 2 or 4 stroke.

This is the general manual issued by Marzocchi, not Beta.

The std rate is .48 and while it is not on the parts fiche of the 2014 RR350 Factory, it is on fiche of the 2014 RR450/498 Racing.
Moreover std outer oil is 370ml (380 for the 2-strokes) and not 330 (as on the Marzocchi manual), so when you try new springs don't forget that.
Even 20 ml makes noticeable difference.

Also I should add that Marzocchi makes mistakes.
Beta doesn't......

I thought i would jump in here, this is a post from the forum on the oil levels, which is correct??

2014 Racing Edition Marzocchi 48s - Initial Settings

Gentlemen: I'm busy prepping a new 2014 250 Racing Edition for a somewhat slender customer, so I had the occasion to swap the springs out on the red-legged Zokes. Without busting into the valve stacks, two things stood out compared to the very similar forks on the GasGas'.

First, I recovered 325cc of oil from each outer leg, meaning that with minor spillage and drip-down there was likely on the order of 330-335cc to begin with. For most single-track applications that volume is more on the order of 310cc.

Secondly, the PFP was two full turns in - most GasGas guys run 0 to 1/2 turn for slower speed enduro/hare scrambles (ie non-desert) riding.

If you're having issues with plushness, the forks not settling for turns, high ramp up mid-stroke and beyond, here are two easy (and free) areas to check

The Zoke 48s on the 300s have .44 springs 475mm in length despite what the Beta specs say. Katoom400's springs were measured at .44 and mine feel exactly the same. So, what is the confidence in the 4stroke specs? Yes, Marzocchi does make mistakes, and Timber is likely correct.

Timber, do yourself a favor and take that fork down completely and check it out. May save you a lot of trouble later.

In this case, I won't insist on oil levels . I based my conclusion on a factory spec sheet where I verified that the valving was the same with my bike's valving (hence I concluded that oil levels should be the 380-2st and 370-4st as on the sheet). I have not measured oil level on a new fork (like Steve).
Also, I know as well of one case with .44 springs (instead of .42).

Hence...

Timber, do yourself a favor and take that fork down completely and check it out. May save you a lot of trouble later.

.... this is the best way to start.
