This would depend on what type of oil you will be using for your premix. The oil base stock is either petroleum, semi-synthetic or synthetic oil and is mixed with gas at a ratio ranging from 16:1 (petroleum) to as high as 100:1 (synthetic). I personally ride a 2001 Kawasaki KDX200 that I run Yamalube 2R at 36:1 with no problems. Although synthetics say you can mix them at 100:1 I would not, that seems way too lean to me.
40:1
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.
It's a dirt bike that uses a 2-stroke engine.
Your bike is a 2 stroke. since you are mixing gas and oil together oil naturally blows out your tail pipe. if this is happening, then there is nothing wrong with your bike, unless it is a 4 stroke.
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.
Two strokes can accelerate faster but it depends on engine size
No we can't use 100cc 4 -stroke dirt bike race against 85cc dirt bikes.
4 stroke
for a bike the ratio is usually 32:1. I mix it right in the gas can. I use 20l exactly of gas and put in 625ml of mixing oil.
depends 2 stroke of 4 stroke and racing bike or a trail bike
A 2 stroke.
if it is a cr 60 you would be fine mixing your gas to oil ratio at 32:1
