Marzocchi fork bleed @ dirtbike magazine

hey just curious... is this just a procedure you do when you change your fork oil ? (like to get all the air out of one of the chambers ) ..OR is this some procedure you need to do after so many hours of riding ? (like bleeding your brake lines) ...thanks for any info (I'm watching this thread now)

This is just for changing the fork oil.

Later,

Quick Question......

I just had a guy replace my fork seals on my 09 wr125 forks, I was about to install them, I flipped them upside down to check where the rebound was set and they made a draining of oil sound for about 3 seconds.....I don't remember them making any noise when I removed them originally. Is that normal or is there a massive amount of air inside still??

Help!

A big airspace in there is normal.

Thanks!

You need air space in there for things to function properly. The question is how much air or more specifically how much oil is in there. Hopefully, your "guy" replaced the oil when he did your seals (unless that oil is brand new) and measured the correct amount he put in. Next time, take a shot at doing the seals yourself, it's pretty easy once you have the info at hand and a lot cheaper than paying someone to do it. Unless you factor in the time it takes you to do it the first time. Then, it might not be cheaper. You can also make your own tools for measuring fluids and clamps, but that manufactured stuff can be nice.

He said he has a feeling they might be a bit stiff as he put 340ml of oil in because he didn't have a factory spec.

Service manual - for everything, but the WR, but I got to imagine the forks are the same as it looks like they changed all of them for '09 - http://husqvarnaoutlet.com/repair_manuals
and your owner's manual has it, I believe. Take a look at it, my '06 manual is a bit tricky with every language being on every page, but if you look long enough you can find torque spec and fluids numbers. If you got one with the bike.

Anyone know where I can get the 19mm fork plug/cap for the 50mm shiver forks? The one I need is the plain silver plug/cap not the red one..

I have these forks in my 2010 310, a while ago I had them serviced and revalved and am constantly blowing fork seals, they never leaked before they were serviced but now I am lucky if I get two rides in before they leak. Any suggestions??

Reads like maybe they either did not change the seals and damaged the old ones taking apart/putting things together or they replaced the seals and damaged them putting it back together. It can be easy to damage the seals. It's an easy job, but if you are lazy they can be comprised. Maybe you have too much oil as well.

and if you are blowing seals over and over, either you're getting the wrong seals or the tubes are damaged or the oil thing again. Are you jumping things more now?

Riding as slowly as I always did, suspect too much oil. Is about 300ml per leg correct.

300ml sounds like a good starting point but be aware ... The oil amount helps set the function of the forks ... Less oil means more air and air is compressible so a softer feeling fork action is obtained ... I run about 280ml or as little as 240ml ...

Did the forks feel really stiff? If mine had that much oil, I'm ready for ama sx track style jumping ...

Once you get by the seal issue, you might wanna adjust the oil amount ...

Yep the feel quite stiff, I'll try 250ml as a starting point and can add more if needed. Thanks for the advice this really is a great site.

I'm just going to bring this back once again. I've never worked on these forks before, so this thread has been invaluable.

I pulled my forks apart last night to adjust the preload, and noticed that one of the bladders was quite swollen. When I removed the valve from the top, there was a lot of air pressure released, and the oil level was down below the holes. The other one was fine.
No problem, it's a chance to get new oil in there, and learn something new, but I'm wondering about the oil level in the outside chamber. I see there has been some discussion, and wondering if anybody has come up with something that they're happy with?
The manual says 320 ml, but when I drained them, only 125-150 ml of oil came out, and it looked a lot heavier than the oil in the cartridge.
Any thoughts?

I have been very happy with 275cc's for off road use.
