Not a reply...Just more data............................

If you get the opportunity to take apart an engine very often you may notice that the bottom end of a two stroke almost always has a substantial amount of oil laying in the cases. Even in engines that have been run at leaner oil to gas ratios (50:1 to 100:1) there is plenty of oil. The other internal parts of the engine also are well coated wet with oil. It doesn’t matter if the motor is air cooled or liquid cooled – the internals of the engine are still coated. Much of this oil may accumulate at idle and during periods of low rpm running. Once you get the motor spinning faster and it is under load, that extra oil in the case may finally have a chance to become suspended again in the fuel and air mixture and perhaps be burned.
Many people will rev their engine to clear that oil (that plume of smoke they get at startup or after idle) and refer to it as “cleaning out” the engine. And that is exactly what is happening. That oil – which has become separated from the fuel has gathered in the cases and is standing by waiting for some serious turbulence to get it up the transfer ports and into the cylinder where it can finally be burned. Too much oil in the gas can lead to additional problems like carbon deposits on the piston crown and cylinder head, sticky rings, fouled plugs and wet drippy black gunk (unburned oil) coming out of the joints of the exhaust system.
It is probably best to avoid sustained periods of idle, or very low rpm running under no load. It is also probably better to choose a lower gear (for instance 3rd at 5000 rpm instead of 4th at 3800 rpm) and let the motor spin faster when driving at slower speeds since there in less likely a chance of the oil not finding its way to the combustion chamber. It is my opinion that if you use top quality oils (synthetics are the best) you are only throwing away money and making more smoke by running more oil through the engine than it needs. I have had good luck by always using the same oil to gas ratio and the same oil brand.

RICHER? LEANER? WHAT WORKS AND WHY
Let’s see … your bike is running on the rich side, so you put less oil in the gas to lean it out. Wrong.
Or maybe your bike is running a bit too lean, so you figure that if you put more oil in the gas, that should take care of the problem. Wrong again.
You would be surprised at the large number of riders who don’t have a clue what to run in their two stroke. I know; dozens of people write my DON’T ASK column asking that question.
Many dirt bikers are mixing their gas at ratios as high as 75 to l, or even 100 to 1 with the new generation oils, in the belief that their bike will put out the most horsepower at a higher ratio. Riders who foul plugs all the time, are put­ting less oil in their gas/oil mix, in the belief that the oil is fouling the plugs, and many racers are trying to solve “too rich, too lean” problems by changing the gas/oil mix in­stead of the jetting.
There are a few good reasons to run a fuel/oil mix at ultra thin ratios in a two stroke. High ratios such as 100 to 1 are usually environmental reasons, such as for outboard boat motors. The exhaust of an outboard motor goes directly into the water, and environmental­ists are worried about the oil in the mix polluting the lakes and rivers.
There’s a myth that the less oil you use in your gas, the more horse­power you get. Conversely, many dirt riders actually forget to put any oil whatsoever. We know of one guy who forgot to mix oil into his gas and actually rode it for two hours without seizing it. All the bearings were ruined and the piston was worn out, but it didn’t seize!
Actually, you can get more horsepower out of a two-stroke engine with enough extra oil in the gas, because the oil provides a better ring seal and, therefore, more compression. People think that gas burns more efficiently with less oil, and therefore you get more performance. It almost makes sense if you look at that one statement alone.
The seal of the piston is critical. If you remove the lubricants from the gas, the viscosity of the mixture becomes lighter and more prone to vaporization. With a lean mixture, there is less oil to seal the rings. The sealing of the rings has more to do with the performance of the engine than the possibility of having better-burning gas with an ultra-lean gas/oil ratio.
The old fashioned two-stroke oil that was on the market years ago, was designed to be run at 20:1 and was basically petroleum with a few (very few) ad­ditives. Then, when high-per­formance oils came along, they cost more to make and sold for a higher price. They got into these high mixing ratios in order to jus­tify the higher prices.
If you do foul plugs, it is more than likely caused by poor jetting, not a bit too much oil. If you get your bike jetted correctly, have a fresh plug and a strong ignition system, you won’t foul plugs.
