That spring is pretty wimpy. I think even at 120 lbs you've got to add 30 lbs of air pressure, at least according to the manual.beefmagic said:I'm looking to pick up a 06 Z1 light, but I'm concerned that I may be too light for the stock coil. I weigh 140lbs. Any other light weight riders running a Z1 light or is the Z1 SL the way to go at my weight?
Granted I weigh 200, I am just running about 5 lbs less than they recommend.beefmagic said:Thanks guys. I'm not sure I trust Marzocchi's manual too much. I've heard of too many people throwing marz's recommendations out the window when it comes to air pressures, (this was in regards to the 66sl).
I read on another thread that a heavier person was running very little air pressure and it was still a little too firm. Maybe it was because the fork hadn't been broken in yet.
I'm 175 and with no air pressure I only get 22% sag. It seems to be different for a lot of people. There is a discussion on this a few topics down.beefmagic said:I'm looking to pick up a 06 Z1 light, but I'm concerned that I may be too light for the stock coil. I weigh 140lbs.

I think from another thread I remember you mentioning yours is an OEM version? I wonder if it's got dual springs because the pressures you referred to sounded like my old Z150 with dual springs. Or maybe it's just got a significantly heavier spring.coolatt said:I'm 175 and with no air pressure I only get 22% sag. It seems to be different for a lot of people.

It's only coil on one side. That side has no ETA. The other side is the RC2 damper. I wonder if there are different springs on OEM versions depending on the bike size. My coil is yellow if that's of any interest..Danno. said:I think from another thread I remember you mentioning yours is an OEM version?

Here are the Z1 Light ETA pressures out of the 06 tech manual
Rider's weight
Ibs 120 ÷ 155 155 ÷ 180 180 ÷ 210 210 ÷ 220+
Positive air pressure
psi 30 ÷ 40 35 ÷ 45 42 ÷ 52 52 ÷ 65
Yeah, I agree that the manual is pretty confusing. Just from personal experience with friends that have the 66 and Z1 Light ETA the Positive Air pressure ranges seemed to apply. I know they're all running higher than 15 psi. There's no Negative air on these forks though. I know one friends 66 L ETA practically sags under its own weight without air.coolatt said:It's only coil on one side. That side has no ETA. The other side is the RC2 damper.

To me these numbers seem to mean that the positive air numbers would be for a strictly air sprung fork. Air preload is what the coil forks have. I had to read the online PDF a few times to understand it.
Anything over 10psi in either leg and I get no sag. Maybe if there was no oil in the legs I could see putting in that much air as there is more volume available. Which asks another question, what should the oil heights be. From the topic a few posts down it should be 60mm in each leg. Marzocchi's fork info is pretty brutal. Sram's fork manuals are much more informative
What did they tell you?.Danno. said:The only oil level info I've obtained is by taking directly to Marzocchi. Their website tables only show volume - at least the last time I looked...
Don't know about that particular fork, but I just put in a request for the 66RC2X levels (a friends brand new fork that has lost rebound) and I included the Z1 L ETA too. Probably take a couple days like usual to get the answer, which is about the same as contacting them by phonecoolatt said:What did they tell you?
