I have a 1986 rm 250 and I mix it 35 to 1 I just got the bike rebuilt then once its broken in I was told go 50 to 1
I would stick to around 50:1 almost always, you can lean the oil out alittle and go 40:1, but the leaner you go the more chance you take on friction building up and then the motor will sieze. Almost everything I own that is two cycle (minus my old chainsaw) is 50:1 and the chainsaw that's 40:1, I run it at 50:1 and it runs fine and alot of power. I would check the spark plug after 3-4 hour of riding and see if it still is pretty clean and then go 40:1 if the spark plug is getting gunked up.
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.

50:1
40 to 1
32 to 1 32 to 1
40:1 from what I've read
no becaues it`s totally diffent.
Using fully synthetic motorcycle 2 stroke oil, the ratio is 40:1. Ie, 40 parts of fuel to 1 part of oil. That means 25mls of oil to 1000mls, (1 litre), of fuel. That is the ratio all the time. Change the fuel air ratio if any problems with fuel fouling or lean running symtoms.
For as long as I have been riding the mixture ratio of a KX125 is 32:1 dont let anyone tell you different.
It is when the "correct" air to fuel ratio is used to completely burn the fuel in question in an internal combustion engine. If exactly the correct amount of air is used this is called the stoichiometric mix.
there is no ratio they are oil injected there is no ratio they are oil injected
The correct fuel oil ratio is 50/1.
