Default Re: what did you do to your motor bike today?

I am not understanding how putting too much oil into your tank could possibly result in a fuel/ air ratio of 50:1.
The engine would not run at such a lean ratio. common ratio is 14.7 to 1.
14.7 parts air to 1 part fuel.
Many modern engines are tuned to run at 15:1, some even 16:1 which is ungodly lean for an IC engine. All in the name of a hotter burn and reduced tailpipe emissions.

Perhaps a 50:1 fuel to oil ratio?
Switching from a 100:1 fuel to oil ratio to a 50:1 ratio certainly would necessitate re-tuning the carburetor as the 50:1 ratio would be heavier than a 100:1 ratio and flow through the fuel ports in the carburetor at a slower rate.
