Name that fork (retro)

mathematics

Just got the old mountain bike down from the hangers - not used in years!

I'm prepping it for a run to Dalby in a couple of weeks. I'm new to cycling in general but been road cycling mostly since getting back into it and now giving the mucky stuff a go with a 14 yr old cheapo bike .

The fork is a Marzocchi Bomber with Z4 on the serial sticker - I think it's an air fork as it has schroeder type valves on top of each stanchion. I think it's a 2000 model with an MG arch and open bath technology apparently. I've measured the travel which appears to be around 70-75mm. I would like to know what fork it is so I can get the manual and make sure it's running ok and adjust if necessary. So gear swears on a postcard please....

I've attached some pics. Beware it's an old bike so nothing pretty sorry







Thanks

Chris

Looks like a Marzocchi Z3 Flylight.

Oh, you said Z4 ;-)

But they are all quite similar in terms of servicing - oil levels though are the bit you need.

I'd go with a Z4 as you said.

mathematics

Yeah the serial sticker says Z4. I've found on line a Z4 fLylight air 80mm travel air fork - prob sounds right.

Do I do anything with the air valves?

Oil you say?

What would I need to service? Can I adjust it at all?

mathematics

Thanks by the way supersonic

Not quite sure what you are asking as you have already IDed it.

A 2000 Z4

Add air to set sag. Make sure the oil level or volume is correct.

7.5wt oil. Volumes/levels are on Marzs webby.

Service manuals can be got online with searching - the forks (might have) had an internal rebound adjuster that required a long tool of some description. Were a low pressure air fork so need a low pressure shock pump.

Are actually pretty simple. They used 7.5wt fork oil, which can be experimented with, as can be oil levels.

I had the Z4 bit but pics on the web had different style stickers so was just asking for some more informed opinion to confirm. I'm a rookie

Thanks for that - do i need to buy a proper shock pump to adjust the air pressure can you get away with other (tyre) pumps?

supersonic

You need a shock pump.

mathematics

Thanks for your help guys.

Can I test the air with a normal tyre pressure gauge?

supersonic

No ;-). As all the air will cgo into the pump, so the reading will be zero. Gauges only work once they have been attached then the air adjusted - not before.
