Ethanol In Gasoline Problems
Certain materials commonly used with gasoline may be incompatible with high-level ethanol blends, causing them to degrade and contaminate the fuel. Metals that have been shown to degrade over time in the presence of high-level alcohol blends include brass,(floats & jets) lead, zinc(carb bodies) and lead-based solder.
Nonmetallic materials that degrade when in contact with ethanol include natural rubber, polyurethane, cork gasket material, leather, polyvinyl chloride (PVC) polyamides, and certain thermoplastic or thermoset polymers.
On the other hand, unplated steel, nickel-plated steel, stainless steel, black iron and bronze have shown resistance to ethanol corrosion, with nonmetallic materials like reinforced fiberglass, Buna-N, Neoprene rubber, polypropylene, nitrile rubber, Viton and Teflon meeting acceptable usage standards with E85.

+1 on what gengomerpyle and MFolkes described. But you said it only happens if you leave the petcock on. So at least you can keep it from happening by turning off the petcock until you fix the probable stuck float needle(s). I would also open the oil cap and see if you smell gas in the oil. If you do smell gas there and also notice the oil level went up, then you have contaminated your oil from the fuel leak. Will need to replace the oil in this case.

Also, there's lots of good info on kawasaki.com, including parts diagrams, part names, part numbers, models sharing same part, availability, etc. Here's a link for help with navigating the site and finding information.

Im not a motor guy as you can probably tell. Any oil breather for dummies type of information would be appreciated. Also is there a cure for a stuck float that doesnt involve removing the carbs? Thanks, Chris
Likely NOT a "stuck float."
Would suspect the more common cause, being an imperfectly clean float valve.
Where crud resides at the interface where the pointed tip of the float needle fits into the seat orifice.
Might get lucky by running through a tankful of fresh gasoline with Seafoam added to the gasoline, which sometimes cleans the crud away from the orifice.
Could also try flushing the orifice interface clean by opening the float bowl drain and allowing gasoline to run through the carb and out the drain, which allows gasoline to flow through the interface.
