DEPENDING ON WHAT TYPE OF FUEL YOU USE , IT CAN BE EITHER 40:1 , OR 50:1 .
Premix (mix oil and petrol at a certain ratio) Contact you local Yamaha dealer for the best mix.
run 32:1 pre mix ratio 4oz oil to 1 gal of gass these little engines turn high rpms they need lots of lubrication
50:1 ratio
50:1 ratio
they have oil injection. but if your are not using it, 40:1 is a good ratio.
i mix mine 20 oz to five gallons i think that is a 32:1 ratio
Three turns out from all the way in will get you close
It would be wise to.At 32:1 ratio
50ml of oil to every litre of petrol
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.
I have a 1983 IT175 Yamaha and the fuel mix is recommended by Yamaha at 28 to 32: 1 I use 30:1 ratio. Hope this helps
