That's not a bad idea, would probably need to pull the batteries as well, shouldn't have oil leaking out of the crankcase vent tubes? I wouldn't think so, we used to stand them up in the back of the truck to fit more when we went on trips.

I need to get a sand dune trip planned out. Definitely need to once I get my 500 broke in if I don't before. That's where the four wheelers are the most fun.
