Marzocchi shocks question

The little 86 Yammy Radian that I picked up to restore has a nice set of Marzocchi shocks on it.Since the bike is 24 years old and has spent the last 10 years sitting in a storage unit,everything on the bike is suspect at this point.My questions are as follows: Can the shocks be rebuilt--I have heard they can,but where would I send them or where could the rebuild parts be obtained? The shocks have a small external reservoir-I assume for oil.Can it be serviced? Finally,the reservoir has a small dial indicator that appears to be some sort of adjustment 1-4.Any ideas on how this works as turning it doesnt seem to make much difference,Thanks all for ur input.BJ

You should be able to get parts from Marzocci but you have to hunt and chase. I bought a set on ebay and found all the parts for rebuilding them from Marzocci. I did not buy them because mine are good. You can change the one end from an eye (Kawasaki) to the clevis (Suzuki) to. Mine has an air chamber as opposed to an oil chamber

yep.I spent several hours chasing Marzocchi around the web-have they been bought out by Ikon or somebody?Any idea where the part number on the shock is-cant seem to locate that either.Thanks for the input.bj
