[QUOTE="Rich Rohrich, post: 1328898, member: 16241"] You mean like this gem? :rotfl: You should have paid more attention in chemistry class. ;) Back to the original poster's question. Ethanol based pump fuel is best avoided if possible, but if you have to use it. Consider the following : - draining the fuel from the tank and the float bowl is a very good idea to avoid water accumulation. - store the fuel in the smallest sealed containter you can and keep it cool and dry - test a small sample of your fuel with the oil you use to make sure they mix properly, and stay mixed over time. It's likely they will, but better safe then sorry. - your fuel mileage will drop compared to standard gas - your jetting will likely go to the lean side with ethanol based fuel - it will be harder to jet for good throttle response because ethanol has a fixed boiling point around 173 degrees f and a very high latent heat of vaporization, along with a requiring a different A/F ratio then the rest of the fuel. In short it acts very different then pure gasoline and screws up the fuels distillation curve which can cause jetting issues. - the octane distribution of ethanol based fuels will be very different than pure gasoline, so it's best to tune on the safe side till you get used to running with ethanol. Two-stroke riders who switch to ethanol based fuels without other changes very often run into knock and detonation issues they never had before. -older two-strokes can have issues with the solvent properties of ethanol attacking the crank seals and destroying them. This was a real problem in the early 80s when ethanol started first showing up. The current crop of two-strokes don't have these issues. If you jet really sharp you'll probably see an immediate change in the way the bike runs and will most likely be on the lean side. If you jet sort of close it may not matter. If you keep in mind it will be a little lean you'll likely be safe. If anyone is interested in more of the specifics about alcohol as a fuel follow this link to the DRN KnowledgeBase : [url]http://www.dirtrider.net/forums3/showthread.php?t=115212[/url] [/QUOTE]
