What is the best 2 stroke oil to premix for a 90 polaris?

Stock cylinder with hetrick pipe and with oil injection removed.

would mixing 50/50 race fuel improve performance- what oil to gas ratio?

I use maxima super m

We use amsoil donminator.

how many ounces with a gallon of gas? also will running a mixture of 50/50 race fuel help performance?

There was a thread on. Here that said from 32:1 to 50:1 there was no power gain. You just get more use out of your motor when ran 32:1. More lubercation. I just remember this in that thread.

I run the entire bottle to 4 gallons of gas.Makes it 32:1

Can you run the high octane race fuel with a stock cylinder ,but other mods and improve performance?

amsoil dominator at 40:1 has been the trick for us. I beleive you would be wasting money with a stock engine and race fuel. If you bump the compression and port it you may wanna get 110.
Just dont let pump gas set very long due to the ethanol, it will absorb the humidity and add water to your fuel as well as separate and cause a lean seizure.
Ethanol is bad, really bad, easpecially for 2stoke engines.
