Depending on the maintenance level of you vehicle, the key to your performance may lie with the replacement of your fuel filter. Ethanol is 'almost' bullet proof with regard to is ability to dislodge crud in you fuel tank an lines. If you have it, ethanol will remove it and it will end up in you filter.

If your entire fuel system is 'crudded up' , the dislodged 'stuff' can mess up your injectors. With the continued use of ethnol blends the system should eventually clean itself UNLESS your fuel system was really dirty. Most people don't realize that 'discount' fuel stations buy their gas from 'the lowest bidder', (so to speak), and the octane rating and the cleanliness of what they sell is 'less than desireable.

AND, if you've ever filled up while the 'big, unmarked, silver tank truck' is dumping fuel in the underground storage tanks at that station, you're literally pumping all sorts of crud & water straight into you gas tank. That fact shows up very fast when you fill up a motorcycle that is on reserve. The substandard or dirty fuel will be immediately evident before your front wheel hits the pavement when leaving the fuel station.

Many of those 'unmarked' tank trucks never bother to purge their tank before picking up a load of a completely disimilar type of liquid from crude oil to diesel to 'whatever' is available to cover the expenses of a deadhead return trip to their home base.
