Isn't an Xr80 a four stroke ? If so, there is no mix ratio, if it is a two stroke by some chance, I would say 32 to 1, so 4 oz of oil per gallon of gas.
Around 32:1 depending on the quality of the oil.
I have a 1998 CR250 and i mix it 32:1
you should mix it 32:1 that 4 0z to one gallon.
35:1 is the fuel mix ratio
The mix of fuel to oil ratio is 16:1
1:2
i mix mine 20 oz to five gallons i think that is a 32:1 ratio
50 to 1 ratio
If the banshee hasn't been bored or altered then there is one ratio mix. The gas to oil ratio mix should be 40 to 1 .
it is 3 to 2
the ratio is 999 degress nort
50:1 ratio
