[QUOTE="AARONA, post: 741778, member: 41125"] [b]Lets Beat This Dead Horse..[/b] That's the thing. A lean premix = more gas/less oil. A lean air/fuel ratio = less gas/more air. Both need to be taken into account. When someone talks about rich or lean, make sure you know if they are referring to premix or air/fuel as they are both kind of opposite in their own context. Which is probably how so many arguments start. To answer your question...more oil to a set amount of gas will reduce the amount of gas in the premix. Depending on ratio of course. By reducing the amount of gas, that make a rich premix, but lean air/fuel ratio. (less gas than if the premix were light on oil) Micah[/QUOTE] so then, lets look at it from what the cylinder sees. Lets just assume that I have a properly running machine, at a set fuel/oil ratio, and the bike is jetted properly and the weather is constant and all that. our bike is running good. Now, we use twice the amount of oil in our premis as before. So now I have the same motor, and why would the cylinder see a fuel air ratio any different? It is still going to let the same amount of air as before, and the same amount of fuel, but now our fuel just has more oil, less gas and the same amount od air as before......so because the oil does not contain the same energy as the gas during the combustion process, the oil is taking up space that was occupied by the gas before, so there is a leaner fuel/air ratio as seen by the cylinder compared to the first case.... ok. The lightbulb just finally went on. Glad this site is here. thanks for your post Micah. I'm going riding on my studded up KX250 this weekend on a frozen river in Fairbanks, Alaska down the Iron Dog Snowmachine Trail. You better believe I'll be correcting my fuel/air ratio for -10F...
