most likely, your oil level is too low, or you had the bike upside-down for a while.They work properly and one day I decidet that the rebound is too fast and I try to slow it down and and made a couple of cliks but noting change. Then I realise that it did not work.
If it was that simple it would get normal again after bouncing on it for half a minute...most likely, your oil level is too low, or you had the bike upside-down for a while.
Not neccesarily. When you go to cycle your fork you got slow your rebound down and really compress the fork. If you don't you can be doing it for 30 sec. Also if it's been upside down for a while it will take a bit longer.If it was that simple it would get normal again after bouncing on it for half a minute...
Your fork need some love man, give it a proper service.
That is likely, but it's also an old fork, if it has enough oil the reason is a blown damper, which does happen after years of service. I'm going to go with "low oil" for now though.most likely, your oil level is too low, or you had the bike upside-down for a while.
Yes 220 ml in each leg. Exactly how says in the manual.
really? theyve said the opposite to me when they rebuilt my fork both times.There in fact is the problem....... Even Marzocchi says dont service the fork like that. generally when you measure it out like that you overfill the fork and blow the damper when your trying to use it.
Zokey will tell you flat out... specially on older zokes to measure it with oil height not by measuring the amount and adding.
Yes really, have always done zoke forks by oil height vs volume measurements..... PSecially with older ones you cannot open the cartidges on, you end up never being able to get all the oil out of the cart to begin with, and end up overfilling it.really? theyve said the opposite to me when they rebuilt my fork both times.
I think it all depends how you change your oil. If you just pop the tap caps off and pour the oil out, the oil height is the best way. If you do a complete break down and cycle the cartridge, measured amount is good. I also run a little less oil than recommended also, maybe that's why I don't blow a cartridge. Also we are pretty much accomplishing the same thing, just differ ways.Yes really, have always done zoke forks by oil height vs volume measurements.....

No it's not. Especially if it was serviced incorrectly, or didn't ship with the proper level. The best way is to call marz tech support and get the proper spec, wether it be oil height or volume.Best way to change oil is measure what you took out, put the same amount back in.
Thats just it..... it is phycisally impossible to do a complete tear down on this particular fork... You cannot take teh carts apart to get all the oil out, not without destroying them......... I have done these forks for many years with excellent results and NEVER have I been able to cycle enough oil out to use a volume measurement without the fork being overfilled.I think it all depends how you change your oil.

Sorry shouldnt have said complete. Knew somebody would've caught it. When I take the cartridge I cycle it for a little while. I know there will be some residue left over in the cartridge. Measure it out is just easier for me. It works for me. Also I put less oil than recommended, 300 I believe for the 888, and I put about 290. Even thinking a little less next time. On another point, nice sig, like it.Thats just it..... it is phycisally impossible to do a complete tear down on this particular fork...

This is the technique I learned from barnetts.......... In fact there is a tool made for it.. basically its a syringe with a clip on the end of a tube. The tube has measurements on it to tell you how deep into the fork it is, so you fill it up, cycle it, then suck out the excess.....
Yes air and oil will mix in the fork, but if you put it together with more air in the cartridge than oil, I don't think you can get all the air out of the cartridge. Air should be on top on oil on the bottom, meaning oil in cartridge and air out of the cartridge and on top. Like a upside down bottle of air in the tub. You won't get the air out till you tilt the bottle. If you don't cycle the cartridge to fill it with oil then it's going to filled with air. Then you put the top caps on there is going to be no space on top for the air. The air then stays in the cartridge. This is will explain why you have no rebound dampening when you turn the bike from being upside down. You have to cycle the fork to force oil into the cartridge and air out. This my reasoning, sorry if it sounds confusing. Also no disrespect to the OP I don't know if he can tell he has no compression, no rebound would be easier to tell.It's not as complicated as some people are making it out to be. For the damper to not work at all something must actually be broken / wrong internally. You don't NEED to cycle the damper to get air out, that will all happen when the fork is in use (hello, gravity). Overfilling won't blow the damper either, the only thing it could possibly blow is the seals.

I think you did the right thing by putting the 220ml in each leg.
If the fork has no damping then it is possible the damper cartridge has some problem with it, perhaps something is broken inside. Unfortunately they are sealed cartridges so if something is broken it may be difficult to fix.
If you remove the rebound side damper (the one that does most of the work), you can remove the spring and put it in a tall container of oil and cycle it by hand to see if it is working. I don't have a 66 but on the 888 of the same year you had to be very careful where the topcap threads onto the shaft - there was a red nut that could break the shaft if overtightened. Just FYI, not sure if the 66 is the same.
Well that sounds fairly normal, seeing that the marz specs for years were too much oil. the 888 however is not so critical to a little overfill like the 66 is.... 10ml over and you lose full travel on the 66. One of the more sensitive open bath forks I have worked on.Sorry shouldnt have said complete. Knew somebody would've caught it. When I take the cartridge I cycle it for a little while.

For the record, a 66 takes about three pushes, if that to "purge" the cart, very VERY simple carts in these forks... In fact after letting your bike sit upside down for a night its usually good to go before you hit the trail on the drive over without cycling. They are not bad about trapping air at all.Yes air and oil will mix in the fork, but if you put it together with more air in the cartridge than oil, I don't think you can get all the air out of the cartridge.
