Marzocchi Fork And 2.5 W Oil

[Monstaman]

Afternoon gents, ok, changed my fork oil to 2.5 w oil.

I have a few stats and figures for those interested and a few observations.

Firstly the fork cap with pin fitting is easy to undo, they are not on tight which makes life easy to undo, tech tip is to loosen them off PRIOR removing from the triples.

I did battle with one fork protector fastener but I won.

We drained the majority of the oil through the compression damping adjuster (say 98%) and drained the balance when we tipped the stanchions upside down overnight to ensure full drainage.

Refilled each leg with exactly 480 mls of 2.5 w oil, I have adjusted the rebound damping up and thus far it has had taken a lot more turns in to achieve similar rebound to before which indicates the damping will be much more in my range, I have not touched the compression damping but first impressions are good.

I note at this stage I have not ridden it, will head out shortly when the wind settles down and prior the rain as we have a severe weather warning for 220 mm (8.80 inches) of rain tomorrow

So pics as follows, the Tardis looked like one of those start wars flying fighter

Stats

Spring Wire Diameter = 4.95 mm, supposed to be 095 nm sping

Spring free length = 270 mm

Top of spring outside diameter = 37.08 mm

Inside diameter of spring = 27.18 mm

andi ... you must only use eevoo (extra extra virgin olive oil) in the marzocchis

Righto gentlemen and john

For anyone around the 70 -74kg (154 - 163lb) like me the 2.5 w oil works beautifully with plenty of adjustment, they even makes the swooshing sound per Ohlins!!

The .95 nm spring is probably still too heavy and I can see an investment in a .80 nm however I will ride it like this for a wee while.

I use Motul 2.5 oil, this has a corrected viscosity of 2.45 so in it very close.

The front is way more compliant now which is well cool, if the seat were leather it would be close to a couch

I just checked on the Race Tech websight, the stock spring for the Hyper

with the 50mm fork is a .660 and for a 163 lb rider for street rideing you

should be using a .805 spring and if you race the bike a .870 spring.

so your suspension shouldn't be too stiff? Aloha Alex

Heya Alex, hmmm, there is conflicting info eh, Tony from racetech told me the std hyper S spring is .95nm.

I would like to go one softer in the front if I can, I measured the wire diameter so we have a point to work from so I am gonna dig into it a little deeper.

right if i can find an open bike shop tomorrow there is tomorrows job still want to see what happens when its 35c outside and they are worked hard.

don't they take 550ml tho?? has the travel got to the bottom of the fork yet with less oil?

I did ride (and race) bikes a lot before last year (working on a helth issues for now). I have a Rocky Mt TO set up for xc racing as well as a Specialized M2 hardtail. The Rocky is really sweet, weighs in at 22.5# with the race wheel set on it & climbs like a goat!! It's hard to ride the hardtail after getting off the boinger ;-)

Take care,
Cory
