seriously?, what colour would oil that has been used too much look like?,
what about oil that has been changed slightly too early?

doesn't the grey colour come from the metal shavings?

RM250,

OK Here's my experience FWIW:
We change our oil every 1hr racing, 2-3hrs playriding, it comes out pretty
much the same colour it went in....except if you have rebuilt recently when
it comes out a bit silver/grey from the break in particles....

hmm i get to take this 2 different ways

my RM's oil comes out darker than it went in to the transmission, almost
black but doesn't seem to have any crud in it, i think i put maybe 6 or 7
hrs on the tranny before this change and about 20 hrs on it before the last
change it was basically black when it came out


when we had the CR i changed the oil after we rode it once or twice and it
came out grey! what does that mean - just so i know

the CR always ran well the tranny *seemed* fine never missed a gear the
clutch was crapped out it was digital there was no slip then it just bite in
full tug! - anything to do with it?

- P.S don't blame that crap with the CR on me or my dad i can assure you it
was like that when we bought it/

Sometimes the grey is a result of aluminum clutch plates. My 93 came stock
with aluminum clutch plates, they would "muddy" up the oil pretty quick. I
have since switched them to steel and oil comes out WAY cleaner.

Grey is a sign of water in the oil. After a mud ride on my quad I changed
differential fluids and it was white. Normally the oil should come out the
same color it went in or darker.

Thanks Jeff and andy, i don't have the CR anymore i was just wondering, the
bike looked nice but everything that i seen when i had it and even now says
it has been mistreated by the last owner

what would the oil look like if fuel was getting into it?, i know there was
a problem with the engine in terms of bottom end power maybe its related?

Well, it would smell like fuel. There's pretty much no way you can get
significant amount of fuel in the transmission. Water is another story.

Many oils have dye added at the refinery. Most motor oil will not
have the dye.

BTW, (Bye the Way, fTNIiNA) (for Those Not Instructed in Newsgroup
Acronyms :-) ALL oil starts out as green. Crude oil looks black,
but is actually dark dark green.
Distilate is the only refinery product that loses all it's color.

Tar, which is black, is no longer oil, but what you have left, after
the oils have all been cooked off.

Some fuels are required to have a certain color dye in them, to
differentiate between taxed and non-taxed varieties.

ATF is always dyed red, to keep idiots from adding it to the
crankcase, during oil changes. (or at least let them know what they've
just done. :-)

Many specialty oils have dye added to them to give them
"personality" .

Transmission oil in your bike should be light brownish green if
clean, unless a dye has been added by the blenders at the refineries.

If your oil is dark, it is either dirty or starting to burn and lose
it's lube qualities.

If your oil is silver gray, then it is metal (aluminum off your
clutch drive plates, hopefully) mixed in the oil.

If your oil is milky gray, then you have water getting into the
transmission, either from condensation, sinking the bike, or a leaking
water pump seal.
The thicker and milkier, the more water in the oil. If it is almost
white, then it is very wet.

Thanks for the reply Jim is was excellent info!, my oil comes out dark(er)
does than mean i should change the oil more often?

now that i think about it i would hazard a guess that the oil was green. I
had heard stories about "red deisel" and white diesel that was used in farms
and the owners used to put the red stuff (dyed) in their cars because it was
tax free only for use in working vechicles not for cars. But i think that is
gone now and all fuel is taxed good old Britain!

If the oil turns dark, you should change it very soon. Usually, I
change mine according to riding time, but if it turns dark, I will
change it before I ride again, no mater (whoops, a "mater" grows on a
vine and is red when it gets ripe. I meant "matter".) how much time I
have on the current batch of tranny oil.

The untaxed diesel is not supposed to be used for the highway, since
the highway taxes aren't paid on it. It would be no more fair for the
farmers to pay a highway tax on their tractor fuel, than it would for
us to pay highway taxes on our racing fuel. (This is where the "Sims
Trails Act" money is supposed to come from; a roll-back of the
"highway" taxes that we pay on our off-road fuel.

I was stopped by a patrolman on the trip back from Breezy Hills a
few weeks ago. (We had spent the weekend working the trail.) The
patrolman took a diesel sample from my fuel tank, to check for the
color. He told me that it would have been a $1000 fine if he had found
the untaxed fuel in my highway vehicle.

mater eh?, anyway stop diverting my attention!, yea i guess i will just
sample the oil after each ride through the little hole on the side of the
case, i don't have a window in the case like some.

do :(

have non taxed diesel but i am not sure.
