Hope yours get better as well. Good luck.
Thanks, Moto.

Did you put in the recommended 330 cc or the 325 that came out?

Another question that I should know, but don't.

What is the weight of ATF? Is it all the same? As I recall, there are different types of ATF.

Funny thing is I got 320cc's out of each TT fork on the first drain (spec is 330 also) but the RX3 only gave me the 250. I believe it's due to that cartridge that holds the extra 80, as katflap pointed out.
Possibly if I would have let them drip a few days as Moto mentioned, then it may have given the entire 320-330.
Especially after a couple rides, I feel confident that the correct amount went back in.

Spud, as always, did the homework for us. Check out post 27 here for the info; http://www.chinariders.net/showthrea...t=chart&page=2

Spud's chart is very helpful. Another ATF that Spud has recommended in the past is Valvoline Maxlife ATF, which comes in a little lighter than Mobil 1 Synthetic ATF. Maxlife viscosity@40C cSt is 28.82, whereas Mobil 1 is 34. Both are excellent choices; it depends on your specific needs/preferences.

Good find! Good find, david3921!
Yes....Spud always comes through....wherever he may presently be. We're still currently in a potato famine. ;-)

Like I've said, I've always had spectacular performance from the Bel Ray, even back in my younger MX days when I was far more demanding of my bikes....but I may have to try the Mobile 1 ATF next time around. As Spud pointed out, it's less expensive, easy on the rubber, doesn't foam like the older ATF's I've run, and is readily available many local places....and Lord knows I don't ride like I used to ;-)

Mobil 1 synthetic atf ! I think I even have some left. 204k on that silverado and have changed a.t. 5 times exclusively with the stuff. First time it took 14 qts to replace all the organic stuff (quiet expensive as I remember) but i believe it made all the difference in keeping my transmission alive.

Thanks, David.

Impressive chart.

But what is a centiStoke?

And how does that translate into terms normal people can understand?

And where the heck is Spud?

A centistoke (cSt) is the derived centimeter-gram-second (CGS) unit of kinematic viscosity.

I don't care what's inside those fancy fork oil
DEXRON-VI https://en.wikipedia.org/wiki/DEXRON#DEXRON-VI ATF or AW32 Hydraulic fluid from name brands is economic workhorse in bike's forks

It gets very complicated. Best to just consider it a mystical unit of measurement. The only way it is handy for folks like us to use is in a chart so we can use it to select something thinner or thicker than what we are currently using.

Product Whoopie Oil 10 rates at 28 cS and we want something a little bit thicker. Product Nifty Oil 15 sounds good, but actually flows at 25 cS. So that's not what we would want to buy.

Weight is a SAE rating for lubeication..
forks/shocks work by flow rates that is the
centistroke "CST" rating at 40*c

I have never seen a CST rating for ATF.. but I have
never looked either.... not something i would put in my forks...

the real prob with useing weight.. Is a 10 weight oil
from one company can be the same as a 15 weight from another
the weight rating is all over the place with no real standard..

For a dirt/trail bike...
used in the dirt stay with a centistroke "CST" rating under 18..

There are CST Centistroke charts on the net that give almost
all fork/shock oil from diffrent companys & bike Manafactures oil
in the centistroke rating..

Google is your freind...
