Good idea. This procedure makes a lot of sense. Question, how do you drain the tank, is there a drain plug on it or do you have to drop the tank to drain it, or siphon it maybe? Is Dri Gas the same thing as Sta-Bil?

That's a good idea. What do you think, just some standard motor oil squirted in each cylinder, or would something like marvel mystery oil be preferred? You comment on the fuel brought something to mind as well. If there is any fuel in the tank that did not evaporate it is at least 5 years old now. How should I deal with that I wonder?

  Drain the tank as much as possible.
 What I would do would be to put in about 5 gallons of new gas with an ounce of Dri Gas and some injector cleaner.  I would crank it over till I knew some of the new gas and Dri Gas mix got to all the injectors and every other part of the fuel system.  I'd let that sit in everything for a day or two to dissolve all the gum deposits...Then I would run it for a bit, maybe till it comes up to temperature.

  Then I'd re-drain the fuel tank, clean or replace the fuel filters and re-add some fresh gas.   I'd expect or watch for fuel issues for a few tanks of fuel....5yrs sitting can make problems with the old gas... I recently re-awoke a Suziki DRZ dirtbike after 5yrs...The tank was so gummed up I had to toss it...The old gas had reduced itself to a red putty that nothing would dissolve...

  Dri Gas is a pretty amazing gum disolver, though it is not sold as that.
