What happens when you change the fuel mix in a car?
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.
What should two stroke fuel mix 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. 1. The higher the engine RPM, the more oil they ran in the fuel.
Can you run high octane gas with two stroke mix?
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.
How do you mix gasoline and oil for a two stroke engine?
Two stroke engines burn oil and are designed to do this, and require the proper oil in the gasoline. Mix the gasoline and oil thoroughly. One method is to take your gas and oil can to the gas station and mix right there at the pump. Fill the gas can about 1/3 full and then add the proper amount of oil, then fill the container.
What kind of fuel does a Kawasaki KX250 use?
Kawasaki Specs I believe most run 32:1 but it depends on the owner and if they have rejeted the bike for a different mix. For my bike 90 octane or above is recommended. 91 or more octane is fine. You can run any where from 32:1 to 40:1 with no problems.
What should premix ratio be on Kawasaki KX250?
A trail rider on a 500 that never reams the bike out is probably fine on a diet of 50:1, where a super-fast up-and-coming young future pro that screams an 85 ’till the dogs howl the entire time he’s on the track might not get a full day of racing out of an engine on less than 30:1.

Do you need Super Unleaded on a KX250?
In general, super unleaded is recommended, but I have read a few people mention that a certain model may ping under high stress or load, even when jetted properly. I have seen more than one person mention that on a 2005 KX250.
