you could loose compression ,and not start , AKA flooded engine snydrom , but that would be extrem ,

 

oh thats what could happen thats always fun [img]i/expressions/face-icon-small-frown.gif[/img] i guess ill try to keep all for wheels up right

 

The gas could break down the oil.

 

rolled my polaris a bunch of times.one time i tipped it and it rolled down a 40ft hill into a ravine , landed upside down on the rocks.bent handlebars , broke front rack, fnder, headlight, ripped seat etc.with the help of 2 other guys got it back on its feet, waited 30 min, chcked oil and started it.Drove it 32 miles back home after straightening the handlebars enough to drive.
can't kill a polaris, i have tried many times!
replace all fluids , check battery level and verything should be fine
