Couple scenarios will cause liquid (other than oil) in the crankcase. First, you need to determine if it is, in fact, water. Easy to do, just unscrew the dipstick, hold it up to your nose and sniff it. If there is no definite gasoline smell to it, it's probably a mixture of blow-by gases and condensation from the crankcase vent assembly. ;
The fix for that is to drain the clear plastic tube that is routed from the bottom of the airbox to the ground (exits below/behind the right foot peg). It collects blow-by and condensation from the crankcase and prevents it from re-entering the engine. If it is not drained occasionally, it can back up and cause the issue you're describing. The tube has a plastic plug in the end of it which should be put back once the tube is drained. It prevents atmospheric moisture (rainwater splash, dew, humidity) from collecting in the tube. Second, if the smell is gasoline, the cause is probably a faulty petcock diaphragm. Fix for that is a petcock rebuild kit.
