I've been real careful to keep ethanol out of my two stroke bikes and older outboard motor, but it has been easy around here because little or no alcohol is actually blended into gasoline (although state law requires >= 2%).. Only once did I even detect a trace (less than 0.5%) using an EAA test kit. Now I purchase from a Conoco chain that advertises on their billboard "No Ethanol" so I don't bother to test.
Of course, most any bike or racing vehicle, two stroke or four, can be jetted to run on straight alcohol. Seals, etc. will have to be replaced with ethanol-safe ones. In some cases the diluting effect on cylinder wall lubrication must be taken into account. Shouldn't be much of a problem on hard-chromed (Nikasil, etc.) cylinder walls. Will run cooler depending on power output.
Diaphragms in older boat pumper carbs can be a real problem, as well as fiberglass gas tanks on boats and bikes.
Completely impractical for my Rokon RT-340 and it’s 60’s Sachs engine.
Here we have no real choice about the damn Ethanol, it’s mandated, and comes from Kali. refineries, where it’s also mandated.
Once I get the engine back in the frame I suppose I will have to buy race gas, at what, about $9.00 or more a gallon?
I might be able to get 100LL Avgas, not sure what issue that might create.
I think it will work OK since I will be adding two-stroke oil.
As to my cars, that’s a bigger issue.
I am NOT putting Ethanol into my vintage Webers!
The bike is only ridden locally, but the cars need to be able to go long distance.
E15 alone is enough reason to vote against Obammy, what has Romney said about this %@#&!, if anything?
