36 parts fuel to 1 part oil..........
The gas-to-oil mixture ratio for a 1989 Yamaha 125 is typically 32:1. This means you should mix 4 ounces of two-stroke oil with 1 gallon of gasoline. Always refer to the owner's manual for specific recommendations, as variations may exist based on the model or modifications.
DEPENDING ON WHAT TYPE OF FUEL YOU USE , IT CAN BE EITHER 40:1 , OR 50:1 .
run 32:1 pre mix ratio 4oz oil to 1 gal of gass these little engines turn high rpms they need lots of lubrication
Premix (mix oil and petrol at a certain ratio) Contact you local Yamaha dealer for the best mix.
50:1 ratio
50:1 ratio
they have oil injection. but if your are not using it, 40:1 is a good ratio.
Three turns out from all the way in will get you close
50ml of oil to every litre of petrol
It would be wise to.At 32:1 ratio
i mix mine 20 oz to five gallons i think that is a 32:1 ratio
The blaster 200 is a 2-stroke, therefore you need to mix the gas and oil, trying running a 50:1 ratio, 50 parts of gas to one part of oil.
