My fourwheeler ran good after I changed the head gasket for the longest, until it kept taking more and more coolant, because the resevoir would never stay full.  Then it lost all power one day when I rode it, and after that, it would not start.  I took the head gasket back off and water ran through the rings into the crankcase.  Now I definently can not get it started.  Is there a crankcase drain?  How would I get the excess water out?  Is there suspose to be oil in the crankcase or does the oil from your gas and oil mixed lubricate the crank and bearings through the rings??  I'm a four stroke kind of person so I am confused.  

THE OIL FROM YOUR MIX IS WTAT LUBES THE CRANKCASE,AND
AN AIR GUN WILL GET MOST IF NOT ALL WATER OUT. OTHER
THAN THAT AIR DRY IT OR HEAT GUN TO EVAP. WHATS LEFT.
