Does Opti-2 change air/fuel mixture?

I have searched and searched. I remember a long time ago reading in a thread that running 100:1 changes the air/fuel ratio. I can't remember if it made it leaner or richer. Can anyone help me?

My fuel to air ratio was perfect with the clip on the very top notch and with the sbp chamber. Then I put my stock pipe on and it is running rich. I am going to buy a smaller jet from SBP but I was wondering if the Opti-2 is why it is running rich.

The more oil you use it will make a lean condition with the fuel. Less oil more fuel.

Yup. What he said!

Just to clarify the last part of your post...you say "Less oil more fuel" meaning, less oil in the fuel/oil ratio = richer fuel/air ratio.

You have to factor in the venturi size on the carb. All that oil has to make it through that tiny orfice.
