I had a boat and motorcycle and I would cut the gas off and run the engines until the gas was out of the carbs when I was not going to be using them. I wanted to get a snow plow for the used Grizzly I just bought but the plow may have to wait a while. The atv has fuel injection and no gas cut off I can see anywhere. Letting gas set in my boat motor destroyed the carb seals once . With fuel injection is there anything to worry about if its not run for a period of time ? I have never had anything with fuel injection before so not sure what I should do if I let it set for a while . I know on warmer days I will run the engine some and try it in the snow to see how it does. Thanks
