It depends on the bike, riding conditions and usage.
Standard factory mixture is 32:1 (for Yamaha 2 strokes)
But with my racing bike, to allow it to perform at peak, we use a synthetic two stroke oil and mix it as little as 42:1 (gas:oil)
32:1 is a great gas to oil ratio for any two stroke motocross bike. Also, a Ratio Rite is recommended for accuracy and simplicity.
well that depends if you have a two stroke or four. if yours is a four stroke, use straight gas. if its a two stroke use a gas+oil mix. you should know the mixing ratio. lots are 40:1 but it could also be 32:1 depending on the bike.

i use a 5 gallon jug and do a ratio of 40 to 1 its a little rich but will run good
there is no such thing as a 1 stroke only 2 and 4
I could be both a 4 stroke runs on regular gas and a 2 stroke runs on a gas oil mixture.
it smokes out the exhaust...
40 to 1
You need to run one gallon of gas with 4 ounces of two stroke oil.That is a ratio of 32:1.
well I have a 2000 Honda 70R and it runs straight gas its a 4 stroke not a 2 stroke.
if you have a 4stroke dirt bike you run straight gas ,if you have a 2stroke dirt bike you run mixed gas
you only use mixed oil if its a 2-stroke dirtbike
