im not sure how much it helps in the long run but id imagine it cant hurt but ive started spraying fogging oil in my engine after each ride, i blow the water out as good as possible then while the engine is still running ill spray a several second burst through each carb. then after i shut the engine off, ill spray more fogging oil into the engine while turning it over. ive seen guys pour straight 2 stroke oil down the carbs after a day in the salt water. i also run my oil mixture at around 34-36:1 for more cheap insurance.
