What gas does 2-stroke take?
unleaded petrolTwo stroke fuel is basically unleaded petrol mixed with 2 stroke oil. The oil to fuel mix ratio should be specified in your engines instruction manual. The oil in 2 stroke fuel is extremely important in lubricating your engine as two stroke engines do not have an internal oil reservoir.
What gas does a 2-stroke use?
Gasoline that is 89 octane or higher is specifically recommended in engines that are two stroke and air cooled. Gasoline may contain a MAXIMUM of 10% Ethanol. Two stroke air cooled engines are approved to use a 87 octane rated clean gasoline in emergency situations.
What happens if you mix 2-stroke wrong?
What happens if the mixing ratios in a 2 stroke engine are incorrect? If you put too much oil, it can generate additional carbon build-up, making it difficult to start the engine, blow excessive smoke which is particularly bad for the environment and may (with time) cause the engine to stop operating correctly.
HOW LONG CAN 2-stroke gas sit?
Once a seal is broken the fuel has a storage life of six months at 20°C or three months at 30°C. As stated earlier, “fresh is best” so be sure to mix smaller batches more frequently. Head over to the front page and you'll find a handy calculator to help you get your mix right.
Why do 2 strokes need mixed gas?
Unlike a four-stroke engine, a unique feature of a two-stroke engine is that they do not have an internal oil reservoir. Instead, two-stroke engines require the owner to mix oil into the fuel at a predetermined ratio in order to ensure the engine receives adequate lubrication during operation.
How do you mix 2-stroke?
It's simply 40 parts of fresh, unleaded fuel with 1 part of semi-synthetic 2 stroke oil. Although that might sound hard to measure, it's actually an extremely simple process. You should NEVER try to mix a 2-stroke fuel in the fuel tank of a machine.
Can I use regular oil to mix for 2-stroke?
Can I Use Engine Oil for 2-Stroke Mix? Engine oil and motor oil don't lubricate as much when they're exposed to gasoline. You can use engine oil temporarily, but it will cause the parts to grind together with constant use. Engine oil also creates more pollution than 2-stroke oil, which burns clean.
How can you tell if a dirt bike is a 2-stroke or a 4-stroke?
Here are some easy ways to tell if your engine is two-cycle or four-cycle:Look at the fuel cap. ... Look for stickers labeling the equipment (e.g., "Four Cycle" or "No Fuel Mixing").Look for an engine oil fill cap. ... The Operator's Manual will have engine fuel and oil information in it.
What is the best mixture for a 2 stroke dirt bike?
Most owner's manuals will tell you, but ratios between 32:1 and 40:1 are common. Thus, your mix is 40 parts gasoline to one part oil. If you're working with the metric system, it's easy: 10cc of oil to 400cc of fuel.
What is the best 2 stroke mix ratio?
Most modern chainsaws, string trimmers, leaf blowers and other small-engine two-stroke equipment recommend a 50:1 oil mix ratio, but some recommend 40:1 and older two-stroke equipment might even call for 32:1.

I just picked up a new 85SX for my son last night and haven't mixed gas in over 25 years and even then, my Dad was doing it for me...they told me to mix at 40:1. Can anybody tell me what how much oil that is PER GALLON of gas?
k2rider
Thanks....I went out and found my ratio-rite in the garage....couldn't be much easier.

What Does 2 Stroke Mean On A Dirt Bike?
2 stroke simply means that the engine completes 2 strokes (up and down for one full revolution) for every “power” cycle. This means that every time the piston comes up in the cylinder, the spark plug ignites the air-fuel mixture to produce combustion and “propel” the piston back down.
Which companies still make 2 stroke dirt bikes?
The companies still producing 2 strokes are: Honda, Kawasaki and Suzuki stopped selling 2 stroke 125cc and 250cc motocross bikes back in 2007, give or take a year or two.
How long do dirt bikes last?
Every dirt bike requires routine maintenance if you want it to be reliable and last many hours. No matter what kind of bike you ride, 2 or 4 stroke, the harder you ride it, the shorter the service intervals will be. Piston rings might only last 5 hours on a 125 2 stroke if you’re holding it wide open on a motocross track.
What is the best dirt bike for kids?
The Yamaha PW50 is the tried and true “first dirt bike” for kids ages 3-6. It’s oil-injected, so you don’t have to mix gas (just pour the 2 stroke oil in a small reservoir tank). The Kawasaki KDX50 and Suzuki JR50 are comparable competitors to the PW50 if you don’t want a blue machine. They’re just harder to find.
How long do piston rings last on a 125?
Piston rings might only last 5 hours on a 125 2 stroke if you’re holding it wide open on a motocross track. But if you trail ride the same bike and are much more conservative on the throttle, you could get up to 50 or 100+ hours on a stock top-end.
Why don't people buy 2 stroke bikes?
Tend to vibrate more (newer models are counterbalanced) Smoke/smell more. KTM and Husqvarna, as well as Beta have been raising the bar for off-road 2 stroke dirt bikes.
What is a good 2 stroke bike?
Examples of great 2 stroke bikes if you’re new to riding would be a Beta 200RR or XTrainer, which are both on my list of best beginner bikes . You’ll be able to focus more on learning proper riding technique rather than trying to control the power.
How long does it take to change oil on a 2 stroke?
People believe that the oil just rushes right through a two-stroke along with the fuel, but that just isn’t so. It can take 90 minutes or more for the oil migration through a two-stroke to result in a complete oil exchange on a slow trail ride, and even as much as 5 minutes for a full-throttle 20 minute moto.
What is the ratio of oil to crankcase?
With that said, to have that amount of residual oil in the crankcase at 50:1 (a ratio made popular by magazines and oil bottles), you can’t be riding very hard, or your bike is jetted richer than necessary simply to deliver enough oil. I arrived at a 32:1 oil mix ratio for my bike with my riding style because that is the amount that gives me the proper amount of residual build-up.
Why does oil not burn out when jetted?
The oil eventually makes it into the combustion chamber, where it is either burned, or passes out the exhaust. If the combustion chamber temps are too low, such as in an engine that is jetted too rich, the oil doesn’t burn completely.
What happens when an engine is jetted too rich?
When an engine is jetted too rich, the excess fuel leeches heat from the combustion process, causing the combustion chamber temperatures to be too low to effectively burn the oil, or even completely burn all of the fuel. The result is spooge and deposits.
Why is mix ratio important?
To understand why the mix ratio is so important, you have to understand what happens to the oil in your fuel when it goes into the engine. While the oil is still suspended in the liquid gasoline, it can not lubricate anything. It has about as much lubricity at that point as straight gasoline.
How does oil mist affect an engine?
The oil mist is distributed throughout the engine by the spinning crankshaft and the moving air currents to coat all the internal surfaces.
Why do small bore engines need more oil?
Small-bore engines require greater oil concentrations than larger engines to achieve the proper amount of residual build-up, because they rev higher and have higher intake velocities. Along the same lines, someone that pushes the engine harder, and keeps the revs higher, also needs to use higher oil concentrations to achieve the proper residual build-up.
What is the best fuel for motocross?
Most non-ethanol based fuel is rated at 90 octane and recommended for Motocross bikes. One type of gas to avoid, if at all possible, is ethanol-based. Yes, it is difficult nowadays to find gas that's not corn fed especially in certain parts of the country or during a specific time of year.
Why is ethanol fuel bad for engines?
The big concern using ethanol-based fuel is corrosion. Ethanol attracts moisture which overtime corrodes vital engine parts. Therefore, burn off all ethanol-based fuel in the tank, drain the tank or add a fuel stabilizer if left in the tank for long periods. Ethanol-based fuel eventually gels and clogs the jets.
Can you blend 87 octane with 92 Techron?
The easy answer is any and all of the above work for your 4-stroke or blend with premix for a 2-stroke. Whether you go the cheap route and grab some 87 octane or think a few bucks more for the 92 premium Techron infused ammunition glides you along faster it all pretty much does the same thing.
Is racing fuel good?
As for racing fuel it's expensive, smells pretty good and if you're reading this it's unlikely to provide any benefits because mostly the pros have the means, the skills and bike set-up to squeeze out the minor performance gain from racing fuel. When you're facing the best riders in the world at an Outdoor National, racing fuel indeed might be the difference between first and second. But when you're lining up alongside local amateurs and weekend warriors, the money saved on regular 87 octane gas helps buy an aftermarket upgrade part that serves you much better on the track than racing fuel.
Do dirt bikes run better on fuel?
We won't debate the merits of the additives. Besides, whatever is added post-production ain't much. But, some people swear their cars, or their dirt bikes, run better on fuel from one company compared to what's offered from another or higher octane burns smoother than the cheaper stuff. What we're saying is don't run yourself mad tinkering with different fuels for that racing edge. Fiddling with the tire pressure makes more of a difference than the gas used on race day.
