This year the fuel doesn't seem to go bad as quickly as it has in the past several years. All riders are given a few tips when they pick up their bikes; those who ride infrequently are told to keep a minimal level of fuel in their tanks. Basically for those who do not ride at least once every few weeks my advice is for them to bring the bike home nearly empty. If planning on riding 60 miles, drive to the gas station and put in a few gallons only. That way each time they ride they are using relatively fresh gas. Not only does the ethanol blend cause the mold, but the deteriorated fuel doesn't allow the bike to rev easily - I'm guessing because of a longer burn time. For those who drive or ride regularly, and have newer machines with fuel injection don't have these problems. Whether it is the ethanol, the mold, the propensity to hold water, the age of the fuel, or any combination of them isn't clear, what is clear is that the problem with many things I repair comes from this category. Coincidence?

Ethanol does absorb water. something that you have to keep in mind if there are breaks between uses. Bill USA Jul 2015 #8

Ethanol injected as a knock suppressant into a high compression engine may yield benefits. lumberjack_jeff Jul 2015 #20

the high compression is achieved by use of turbo-charging not fixed by stroke. Bill USA Jul 2015 #21
