I pull the battery, put a mixture of Stabil, marvel mystery oil, and Sea-Foam in the gas tank and then top off the tank with non-ethanol fuel.
I pull the plugs on 4 stroke types and pull a few drops of 5W-30 in the cylinders and turn it over a few times.
If it's not a BS, I open the drain screw on the bottom of the carb bowls to drain them dry.
They stay in a garage that gets a 'little' warmth from the house.
Today's hope is to look at the GTR some more. I had the carb covers off at the time of the accident. I'm starting to think it might have run a bit while laying on it's side and gotten dirt past the left carb???
The left cylinder head had about 4 cooling fins broke off so that will get pulled anyway for replacement.
