The Yamaha manual suggests 20:1-24:1, however, most people say to use somewhere between 32:1 - 40:1 as long as you're using good quality fully synthetic oil.
Premix (mix oil and petrol at a certain ratio) Contact you local Yamaha dealer for the best mix.
I believe Yamaha came out with oil injection. You do not mix the oil with the gasoline - the oil is in its own reservoir and mixes automatically.
36 parts fuel to 1 part oil..........
they have oil injection. but if your are not using it, 40:1 is a good ratio.
50:1 ratio
No it is a 4 stroke
It would be wise to.At 32:1 ratio
50ml of oil to every litre of petrol
Around 32:1 depending on the quality of the oil.
50/1
What is the gas to oil ratio fot a 1982 Yamaha PW50? Do you need to mix it manually or does it automatically mix together by putting straight gasoline in the gas tank and straight oil in the oil tank?
it should be 24:1 if your using yamalube 2 stroke oil
