Are you sure the carb is clean? Are you running a fuel filter? If both of these check out, check for air leaks, which would make it run lean, and melt your piston. Start it up, and spray some starting fluid around the head and base gaskets, and especially take notice when you spray on the intake manifold. Also check it for cracks. If these check good, pull off the flywheel cover, and see if it is wet with gas, or smells like gas, this would indicate a bad crank seal, and needs to be replaced, so DONT RIDE IT. It could also be jetting, so do a plug chop after cheching all of the above first. Good luck!

i bought a gallon of carb cleaner from the auto parts and you just soak your carb in it for a couple hours.
i would do that first just to clean your carb so that you can rule it out if it continues.and drain your tank while your at it too.start fresh.

Check your float valve, might be sticking or your gas cap vent might be clogged, check petcock...
