When the engine backfires it can send fuel backwards into the airbox, which can then run down into the crankcase through the breather hose.
Before pulling the carbs and following Unfazed good advice, I would pull the airbox cover and have a look. Also remove the plug caps (they unscrew) trim back all the plug leads about 1cm and refit or fit new ones.
Pull the spark plugs and turn the engine over to remove any excess unburnt fuel.
Good luck.
