For an 80 cc kawasaki dirt bike what kind of oil mixes with the gas and in what ratio and what kind for engine oil?

Hi David:
Chainsaws are 2 cycle engines and must have the oil mixed into the gas. Modern chainsaws use a ratio of 50:1
Tat is, 50 parts gas, 1 part oil.
Make sure that you use oil that is specially intended for this purpose. The container will usually have a chart that shows how many litres of gas for how many cc of oil.

Find out how many gallons your motorcycle tank holds. Do a little research on the manufacturer and model of your dirt bike. Also find out what ratio between oil and gas is required. Then, do a little math, and find out how much oil to add to each tank. Add the oil. Then add the gas. Adding the gas last will help stir up the oil in the tank.

There is many options to cause this, spark plug failing, dirty carbi, but the most common cause for this would be fuel mix itself (what fuel ratio are you using?) Try decreasing the oil in your fuel mix slightly see if this improves then move to carbi inspection / full clean and new spark plug

Your manual follows, the answer is on page 9.

Oil Mix Ratio:
McCulloch, Poulan & Wen; recommend 40:1.
• 1 gallon of premium fuel to 3.2 ounces of quality 2-cycle oil.
• 4 liters of premium fuel to 100 milliliters of quality 2-cycle oil.

32:1 / 40:1 will be fine.... your choice of pre-mix oil...pick your fav brand . use a ratio-right cup and make it simple

1. Pump one gallon of gasoline into a gas can. Ads by Google

2. 2Measure out the proper amount of two cycle oil in the Ratio Rite.
3. 3Pour the required amount of oil into the gas can with the gasoline.
4. 4Shake the container lightly until all of the oil is thoroughly mixed in with the gasoline.
5. 5Pour the mixture into the machine`s gas tank.

hi mate gear oil wise you need light gear oil i reccomend silkolene,motorex,morris,rock oil for 2 stroke wise you need to buy a mixing bottle of ebay or something with a ratio of 32/1 and i use silkolene comp 2 premix competition oil descent stuff its 10 pound for 1 litre

Yes if you have a 2 stroke. You will need to look at the manual, or somewhere on the bike for the ratio.

regular or unleaded are fine if it is a four stroke engine but if it is a two stroke engine you will need to fill an oil tank also with two stroke oil, or you may have to mix it in a can , see manufacturer for mix ratio.
