How do you mix a 4 1 ratio?
If your mix ratio is 4:1 or 4 parts water to 1 part solution, there are (4 + 1) or 5 parts. The mixing percentage is 20% (1 divided by 5).
What’s the fuel ratio on a Suzuki YZ 250?
My YZ 250 runs at 32:1 which is what’s written in the owners manual. If you don’t have an owners manual, consult your local (Suzuki, Yamaha, KTM etc) dealership and ask them.

What should two stroke gas oil ratio be?
All the major manufacturers produce two stroke racing engines in their off-road motorcycles. Virtually all of them recommended 20:1 or 24:1 mix ratios. What the actual factory mechanics did at racing events was very telling.
What happens when you change oil ratio to 20?
A typical example: you go from a 50:1 ratio to a 20:1 ratio. Your engine will now run leaner, and you’ll have to make jetting changes. You’ll need bigger (in number) jets because the oil molecules are thicker and the flow rate (the amount coming through the jet) is less. Aha! The volume of fuel has changed.

How much oil to mix with one gallon of gas?
You can obtain this ratio by mixing 3.2 oz. of two cycle air cooled engine oil with one gallon of regular gas. Over a period of time oil will separate from gasoline.
What should the two stroke gas oil ratio be?
Two Stroke Gas/Oil Ratios. One of the things you should do, is run high octane gas with any two-stroke mix. When all of the two strokes (the old days) were developed, they all used Castrol petroleum oil at a 20:1 ratio and found that 92 octane gas had the octane reduced to 72 with presence of that much oil.
