Does anyone know about how long it takes for gas to breakdown and gum things up?
I am going on seven weeks since I rode my bike I run 91 octane in everything I own and put fresh gas in the bike before I parked it.I have never had any gas breakdown in anything.Just started using stabil last year because of this forum everything has been treated except my bike (I thought I would get more riding in but its not looking like it) and for some reason I am getting nervouse.
Do you think I should put it in now and run it until i am sure it has gone through the system?
Does it take longer for high octane to break down?
Whats your thoughts???
1. it depends, mostly on the gas itself, and tempatures it is exposed to. How much air and water are able to contaminate it, etc...
2. First I have no idea why you would run 91 octane in the Vulcan, as it runs fine and dandy on Regular...I also would not use Stabil at all..but use Seafoam..as others have reccomended. Either way, I'd put some in the tank and run the bike. Then I'd turn the gas off at the petcock (if you can) and let the bike run till it stops...or...stop the bike and drain the carbs (there is a drain screw at the bottom of each. I'd then pull the fuel line and fill each carb with pure Seafoam or Gumout carb cleaner.
This will ensure that the carb stays nice no matter how long it sets.
3. Higher octane or regular gas can go bad at the same time...alot matters whose gas it is , how fresh it was to begin with, and if it is a "winter" formula or a "summer" formula.
I don't winterize my bike, but if I did, I'd fill the tank, add a bunch of Seafoam, and then, in the spring, I'd drain the entire tank into a gas can for use in the lawn mower, and fill the tank with fresh gas...
Many folks do still reccomend Stabil, and many use it and report "no problems" ...which means nothing really....you can add a teaspoon of sand to your oil and never have a problem...does not mean it's a good idea............
