marzocchi magnum 45

[sasa]

Hi guys.
I have a problem with the front fork MARZOCCHI 45 magnum on my ec 300 2000 i must replace oil, but i do not know how much oil is needed for the proper functioning of the forks and what kind of oil you advise sorry for my bad English and thanks for your help

The best way to do it is to remove the fork cap and spring. Dump and pump the old oil out, then refill and pump the fork until oil squirts out the top. From there, collapse the tubes all the way to the bottom. Fill the fork tube with 5wt or 7.5wt fork oil to 150mm from the top of the tube. I used a small hose taped to a chopstick, marked at 150mm and just sucked the excess oil out. A long hose its best unless you like the taste of fork oil.

What mike said,, but I ran two different weights in the forks,, one weight in the compression side and one in the rebound side.. as those forks each did a separate function.. I believe I ran the lighter 5wt in the comp. and 7.5 in the rebound.. but I also ran rocks/technical stuff.. I also ran heavy springs and light valving..

thanks, Steve and Mike I have a little problem which fork is for compression Right and which for rebound Left I guess about position i have both foks set at 7 cliks if i put on 3 clics is no difference still too soft and does not return anything slower

One cap should be marked with an R, one with a C on the adjuster. If not, you'll find out when they are apart. When pumping the oil, the compression will pump on the down stroke, the rebound will pump on the up stroke.

And your settings will vary greatly fork to fork on these,, not like a normal fork where you set them the same..

I do this on my 99 EC200 as well. I set the fork oil level to 130mm in both forks to resist bottoming out. The old Magnums do really well in the rocks once they're set up right.

And in NY you should know a thing or six about rocks.
