Hi!

How accurate do you need to be when mixing fuel? My KDX needs 32:1 I can
accurately measure the oil in a glass jug, but it's harder to measure out
the gas. I use a 10 liter Jerry can, but I think it holds more than 10
liters if you fill it right up to the nozzle. Am I being too fussy? Does
anyone have a good way of mixing 2-stroke fuel?

Cheers,
Brett

The way we used to do it was for each five gallon container.
How much gas do you want in this can?
Use the approximate amount of oil and add it to the bottom of the can.
Add the amount of gas figured for. Close the top and swish it around twice.
In most cases there will be no difference in the exact ratio as long as you
are within a 15% tolerance of the mixture you have found to work.
This works if you have to fill a still partially full container.
Just don't let the gas get too old.
Used to keep from forgetting to add oil by adding, then looking inside the
can before any fuel went in a 2S container.
Never made the mistake and don't intend to!
I have seen friends who have. He-- of a way to grind a motor.

I just look at the pump at the gas station to get 19.5 liters in the
can, then pour in 5 deciliters (measured from the scale at the side of
the bottle) of oil.

I don't think it's that important to be extremely accurate unless you
always jet your bike for like any 5 degrees change in temperature or
small changes in humidity and want to extract the last hp of power,
always.

I use the numbers on the gas pump... they are pretty accurate. When it
says 5 gallons (what I need to mix up one bottle of the pre-mix I use),
I stop pumping.

I put 1 pint of Yamalube R in 4.5 gal gas. Works well for me. My brother used
to fill his bike up while on the trailer at the gas station and then add a
'squirt' or two of oil. He never had problems either.

My friend got me a little cup called a Ratio Rite, it is by far the most
easy way of putting the correct ration of gas to oil. It has different
settings for 10:1 up to probably 50 or 60:1. It is so easy, even younger
kids can accuratly measure the oil if told how to.

Brett,
go to your local bike shop (wherever you purchase your oil and tell them you
want a 'Ratio-Rite". Its a graduated container which has pints, ounces and
cc's on one side and a scale on the other showing the level of oil for
varying ratios i.e. 40-1, 50-1 etc,per 1,1.5,2 or 2.5 galon the other.Its
the most foolproof thing I've found for doing pre-mix.
Guessing or getting close may be ok for the weedeater or yard blower but
wont do when it comes to your bike.
32-1 is a pretty rich mixture, most of todays 2-stroke cycle oils are
designed to run at 40,50 or even 100-1.
Too much oil in the mix is as bad as not enough.

Don't know if they're still available, but there's a jug with graduations for
fuel on one side, and oil on a small compartment on the other side. It's
called an "accu-mix" if I remember right (I should, there's one in my shed).
It's really nice if you're paranoid about letting premix sit around to go
stale, because you can mix as much or as little as you need. Full capacity,
"10" on the fuel level, is about 1-1/2 gallons. Of course, it's a complete
waste of time if you regularly go through 4-5 gallons of gas each weekend.

Take the time to clean up the flashing on the faces of the spouts before using
it, or you'll get sprayed when you shake it around to mix it.

I always used a baby bottle for measuring oil. Mainly because I have them all
over the house. They work great for measuring and stay clean with the top on. I
think it also aggrivated the wife and that added enjoyment.

best solution go 4-stroke and pull up to the pump and fill - It is such a cool
perk.

PSST... You can get all sorts of ratios by doubling/trippling or
halving/quartering the amount of gas you add. Double the gas and the
60:1 amount of oil will make 120:1 ratio. Halve the amount of gas and
the 60:1 amount of of oil will give 30:1. Using this method you can
acheive about any ratio imaginable. :)

The pre-mix I'm using is one complete bottle to 5 gals... pretty fool
proof. I do have a ratio rite too though.

Brett,

Hope I'm not off base here with an assumption. You must store your
fuel in a larger container and then put it into the 10L can to mix?

If it were me, I'd take the time to put a measured 10L in the can,
then mark or remember the approximate level. For 32:1 divide the amt
of fuel by 32 (10L/32 = .3125L).

In answer to your second question, at 32:1 you have a little "fudge"
factor, if you aren't exactly right on. Suppose, in your can you
actually have the below amounts of fuel and simply add the correct
amount of oil for 10L at 32:1:

10.25L (10.25/.3125 = 32.8) ratio = 32.8:1
10.50L (10.50/.3125 = 33.6) ratio = 33.6:1
11.00L (11.00/.3125 = 35.1) ratio = 35.1:1

You could be off by an entire liter and I doubt you or your bike could
discern the difference.

Sometimes I think we get a little anal about things, as in:

"I think today I'll run 12.49338 lbs of pressure in my rear tire,
yesterday I had it at 12.49635 lbs and it wouldn't hook up
anywhere......."

Actaully I purchase my oil (Champion, formerly Duralube until they lost the
lawsuit with the additive manuf. of the same name) from my local KTM dealer
in gallon jugs. Its about half the price as compared to buying it by the
pint.

This is related to 'mixing fuel':

I was filling up my gas container a few weeks ago. I had the
plastic container sitting on the tailgate of my truck while I was
fueling up. A guy who was filling his car walked over and stated
that he worked for a petroleum company and that he has seen some
internal correspondence on the possibility of static-ignited
fires due to the difference in potential between the truck and
plastic container. He said that it was a topic of discussion
ONLY but wanted to pass it along. So, to play it safe, I now
place the container on the ground when fueling....

I've heard something similar about filling up boats... that it to keep
the nozzel in contact with the fill spout to prevent a static spark.

If you've got a plastic bedliner then watch out. I saw a ditty on the
news last year about this very thing. I think it had to do with a
static build up and discharge. They made the gasoline ignite w/o any
other apparent source of ignition.

I think the ratio of 32:1 is used because 32 is a convenient number when
using imperial units (ounces, quarts, fathoms and other arcaic units).
If your using metric, it's much easier to mix at 30:1. I have done so for
the entire life of an '83 KX250 and never had a problem.
