Maybe pull the plugs, ground them somewhere away from the plug holes and turn the engine over to expell any standing fuel. Use caution. Oil filter's probably OK as the engine wasn't fired up.
And in your spare time, i-man, consider some fresh float needles and, maybe, new floats. Like you don't already have enough to do on the Frankenbeemer. Bike does keep you outta mischief though.
