Your water pump is gravity feed type, however you can add a vacuum/pressure pulse type pump. Look here : http://www.motorcycle-superstore.com/4/22/423/22375/ITEM/Mikuni-Pulse-Fuel-Pump.aspx
This is just an example, there are many styles and capacities of pulse pump. Look on ebay. You will need to be creative and find an way to tap into the crankcase system. Some engines that use pulse pump will get vacuum / pressure from the valve cover area. The pump works with the natural pressure / vacuum created in the crankcase by piston movement. Good luck
