I have a suzuki eiger that ran great one day and wont start the next. I have checked the gas for water, put in a new plug, blew out the carb and nothing worked. Today im tinkering with it and it ran for about 5 mins then died and wont crank now, checked the oil and it has what i would call alot of gas in it.  

have you or did you roll the atv over?
if so this could explain the gas in the oil.
if not then i would check the valves and the or the cylinder skirt

a bent or burned valve can allow fuel to enter the crankcase, but also a broken cylinder skirt can do this as well.

as well as worn piston rings can allow fuel to pass down past the piston upon compression and into the crankcase.  

no roll over's it ran great, I parked it before hurricane ike came through and covered it so water couldnt get on it after the hurricane the wife was going to ride and it started but ran very rough, died and that was all she wrote.  

no more help needed here thanks for the info. She's running fine and fast.
