Re: 1987 suzuki 140dt storage
If it was winterized last fall then it's still "winterized", so just put the cover on it and leave it, especially since you fogged it and bearings/crank, etc. are still protected with oily film. If it would make you feel better about it, remove each spark plug and spray more fogging oil in each cylinder, crank it over to spread oil, button it up. Good Luck!
