    Hi



    If this is the motorcycle(1972 Aeracchi Sprint) you are intending to use 2 stroke fuel mix for, you should be aware that that model is a 4 stroke. Can you please provide the make, model and year of the moto you need the information on.



    thanks



    regards

What does 50 to 1 ratio means and how much gas and oil I need foe a dirt bike


THIS IS VERY EASY TO FIGURE OUT..THIS IS A RATIO OF 2 STROKE OIL TO GASOLINE MIXTURE..FOR ALL TWO STROKE ENGINES ONLY..MOST TWO STROKE OIL CONTAINERS HAVE THE CONVERSION CHART ON THEM FOR THE PROPER MIXTURE..ALWAYS SPEND THE MONEY AND BUY A GOOD BRAND OIL ..ALWAYS PREMIX YOUR GAS IN A SEPARATE GAS CONTAINER SO YOU CAN MIX IT UP VERY WELL BEFORE USING IT IN YOUR EQUIPMENT..NEVER STORE YOUR GAS TOOLS WITH FUEL IN THE GAS TANK..ITS BEST TO RUN EMPTY BEFORE STORAGE..THIS WILL PREVENT THE FUEL FROM GUMMING UP YOUR CARB AND SUCH..SAVES MANY HEADACHES..PLUS SAFER..

What oil for my xxxxx motorcycle?


This seems to be a very common question, and even if its been written before is worth going through again. This is the simple version as there are a wide variety of bike from scooters, cruisers to racers

Do not use car engine oils they will cause wet clutches to slip.

Motorcycle shops are your best source, auto shops often have the oil but make sure it says motorcycles.
The labelling will tell you but read it carefully.

Four stroke or two stroke?, this you will have to know or find out and is quite important for your engine.

Two strokes burn some oil with the petrol so you need two stroke engine oil which is mixed with the fuel either by mixing with the petrol and putting in the fuel tank or via an injection system with a separate oil tank under the seat or side cover.
Two strokes will also need two stroke transmission or gear box oil, this lubricates the gears and clutch and needs changing when servicing.

Four strokes use the same oil to lubricate the engine, gearbox and often the clutch, so it needs changing often.

There are mineral oils, semi synthetic and full synthetic, with a big difference in price, so your budget may be a deciding factor.
Mineral oils are fine for low stress commuters.
Semi synthetic works in most bikes.
Full synthetic for the high power race bred,or you just want he best.
The weight or "W" value will depend on the bike, the usage, the tempurature etc
For this you need to consult your manual, read the labels and make a decision.
The staff at bike shops will help if its still all confusing, just by telling them the model and where you ride.
Dont forget a new filter at each oil change

1989 yamaha waverunner. I purchased a 1989 25HP Yamaha Waverunner & was wondering how you check the engine oil?


Did you get any instructions from the previous owner? If it's a 4 stroke waverunner there will be a dipstick on the engine block, but I'm guessing it's probably a 2 stroke engine because most watercraft used 2 stroke motors clear through the 1990's. The oil will be mixed with the gasoline when you fill it, bottles of 2 stroke oil can be purchased at most stores that carry oil. Your waverunner can be mixed at 50:1, which equals out to be 2.6 oz of oil per gallon of gasoline. On a 2 stroke engine the engine gets lubrication from the oil mixed with fuel and will burn up fast if straight gasoline is used. Let me know if you have any troubles, but try to get ahold of the previous owner to get some more info.

250 2cycle. What is the proper lube for the bottom end?


all you need on a 2 stroke engine is the oil mixed with the fuel. the oil/fuel mixture lubricates your bottom end and your cylinder which is all that moves in a 2-stroke. if it is oil injected then use a 2 stroke oil rated for 50:1 mix. if you gotta mix it manually then just read the jug. hope that answers your question

On the side of my 86 kx 80 2 stroke there is a hole with a pluge on it do i put tranny or motor oil in it and what fuel mixture should i use(would out board oil work


The plug on the side engine casing is for 10w40 motor oil. NEVER use synthetic lubricants or oil with 'special' additives. They can mess up your clutch. The 10w40 motor oil is shared by the gearbox and the engine because they are a single unit.

Use 4 ounces of two stroke engine oil for every gallon of gas. That will give you a 32 to 1 mixture which is the industry standard. If the outboard motor is a 2 stroke (most of them are), the engine oil is the same. Note the difference > Engine oil verses Motor oil. Motor oil in the gearbox, Engine oil in the gas.

I want to know is it true that 4stroke motor uses only benzin or it can use benzin+oil? I have buy scooter ZN50QT-19 and i dont know which kind of fuel he uses :)He is 4 stroke


All four stroke motors use straight gasoline or benzin. Only 2-stroke engines use a gas (benzin) + oil mix. Even some later model 2-stroke engines run straight gasoline and have a pump that mixes the oil with the gasoline. Most 2-strokes built after the mid-70's have the pump. You can easily by examination of the throttle cable. If it's equipped with a pump, the throttle cable will split from one cable on down to two cables where it enters the engine. Read your owner's manual.

Engine problems on a kx 250 2 stroke


On a 2 stroke bike cause of smoke is due to excess oil in the fuel oil mixture, incomplete combustion in the cylinder or the engine oil finding it way in through the piston rings into the firing chamber. Check the oil levels and clean the plugs, which must be black in color by now, so replace if possible and if engine oil is low, the change the piston rings. Also look up the carburetor jets/nozzles are clean and the engine gets the correct fuel/air mixture by adjusting both fuel and air jets(turns)...sodeep
