This week on the our motorcycle podcast:
Interview with Curt Morgan, who is traveling around the U.S. taking pictures and living nomadic on his 2014 Harley Davidson Dyna. Follow him on RambleOnPhoto.com, IG @RambleOnPhoto, I talk to Josh T about ATV’s. Gas and treatments, heated clothing, and more…
ATV’s hunting, farming, snow moving, and for fun.
What do you know about gas?
The gas we put in our motorcycles expires after 90 days. Most gasoline contains ethanol. You’ve seen it say so on the pump and never paid much attention to it. Ethanol is a is a strong water absorber that attracts water into gas.
Ethanol gas has a maximum shelf life of only 3 months under ideal environmental conditions, and can absorb excess water into gas in only a few weeks or less. Only 2-3 teaspoons water/gallon will phase separate E10 gas. Ethanol blends absorb 40-50 times more water, compared to 100% (non-alcohol) gasoline.
Marine engines and engines that have a vented fuel system (E.G. motorcycles, lawn equipment) and those that reside in humid environments have the greatest risk for E10 water contamination.
If you have less than 1/2 tank gas remaining, we suggest you fill the tank up with very high octane gas (91-93 or better) and quickly run gas through tank.
Use gas additives with caution. Water can also be removed from phase-separated fuel by using some of the newer “water removal” additives in the market. “Water-removing” gas additives almost always contain very strong solvents and alcohol, so always consider other (safer) options before use. When used improperly, additives that contain strong solvents, emulsifiers and/or high alcohol can cause unnecessary damage to engine and parts.
An octane number is a measure of gasoline’s ability to resist pre-ignition, also known as “knocking” or “pinging”.
Since ethanol is considered an octane enhancing additive, if/when E10 sold has less than exactly 10%, the result will be sub-octane gas (less than number stated at the pump).
The additive is called “fuel stabilizer,” and is used to keep today’s low-quality fuels good for a longer period of time than they naturally are. Today’s fuels can go bad in a matter of under a month if not burned. Mixing stabilizer in with the gasoline, and then starting the motor occasionally, ensures that any gas that’s left in the carburetor will be treated, and won’t “gum up.”
If not treated, gas left in a carburetor will dry out and clog the tiny passages that are meant to direct gasoline to the engine.
Another cool trick is to mix stabilizer with the gas, take the bike for a ride (to ensure that stabilized fuel is in the carburetor), then after the ride, turn the fuel petcock off, and allow the motor to continue to run until it runs out of gas. This way, there’s no gas left in the carb to go bad, and all the gas in the tank is treated. – Josh Thompson
And from last weeks show:
Max corrected me from last weeks show on Tires. He says:
I have caught up to the latest episode, and I felt I needed to give one little correction you made about tires. The inflation pressure is not on the sidewall. That is specified by the motorcycle manufacturer, and will be on the swingarm, fork, or owner’s manual. What is on the tire is the load rating for the maximum inflation pressure. I see tire shops using that number all the time, and people getting new tires and say their ride with the new tires is like a logging truck. Check the pressure, and sure enough, it is at the max pressure.
