has anyone ever tried to make their bike run on E85...the fact that it is 105 octane could mean some nice timing advance as well as increased compression. Some people seem to think it will destroy the aluminum parts but the flex fuel vehicles dont seem to have a problem. Also the alcohol burns at a much cooler temp. |

I Imagine that it could be done as long as you could find the components which may be a tad difficult considering the lack of demand. My understanding from being around drag cars is that the motor needs to be purpose built to run alcohol. At least here in the North East, there aren't that many places to get fuel unless you were building a track bike and then it wouldn't matter |

The flex fuel cars & trucks have special fuel lines and filters. Also the injectors and fuel pump different. The E85 will destroy steel and most rubber over time. I would keep that in mind before running it. |

im from the midwest...e85 is everywhere you go....and sure i would need to screw with the carb a little and thats where i was wondering if anyone had experience...and how sure are we that E85 destroys steel?...it might affect aluminum and yah i will need a special fuel line..but would they make flex fuel cars that were going to need new fuel lines and heads every 5000 miles???sure it could be a little extra work...but wouldnt it be worth it to run like 14:1 compression and advance your timing a few degrees as well as run a cooler engine?... |

There was a nice discussion on the XB board. Also, for carbed vehicles, read this: http://www.moparts.org/moparts/picture/print/pages /Vraa.html It explains the ins-n-outs of adding enough fuel to roll E85. You'll probably need a Pingel petcock, and a sacrificial carb or two. Yes, E85 is race gas in disguise. |

In all actuality, E85 is 85%corn alcohol which is drinkable, and 15% gasoline. That is so we cant pull up to the pump and guzzle white lightning at 2.00 a gallon! You have to richen up your mix by a bunch to keep from leaning to the point of frying pistons. |

Jusrfrfun is correct. You will need about 10 to 15% more E85. I see power commander has a switch for a dual program that will work when switching from E85 to gas. Fuel line and pump shouldn't be that hard to swap out. Good Luck Here in Jersey I have to brew it myself if I want E85 LOL |

Jos, Most race gas is pure gasoline with a higher octane rating and other additives. It has the same energy content or more than regular gas. Not the 85% or so that E85 has. Obviously with race fuel, you can run higher compression ratio's than standard gas. The higher compression ratio allows more complete combustion with the higher octane fuel. A lower compression motor with high octane fuel doesn't use the fuel as completely due to lower combustion chamber temps... Brad |
