http://img.photobucket.com/albums/v518/MotoGoalie/overflowtank.jpg Brought to you by Redneck engineering and Budwieser. Materials are ; Turkey baster (buy it at wal-mart of grocery store) Chair bumper (buy it at Ace hardware in hooks and fasteners aisle, take your baster with you....in fact I think they sell them there too. Its a tight fit, which is good) Small length of heavy duty fuel hose, 1/4 or 1/2 ID to fit over baster and Radiator overflow tube. 3 small zip ties to secure that. 4 or so zip ties to secure baster to inside of radiator louvers. WD-40 nozzle bent into a U for venting. If you don't vent this thing it will pop apart. It works perfectly. I've filled it up in several enduros this year from low and slow clutch slipping situations. When the engine cools down it receives the coolant back and you never need to fear the risk of grenading your motor again.
