My first thought when I read this was the head gasket or cylinder sealing in general. Did you just get the motor sleeved? My first guess is that you have a leak somewhere in the cylinder that is back pressuring the rediator and pushing water out of the system. 140 lbs of compression is really low for a Tecate. My 86 (Although Modified + KX Headgasket) has 225 Lbs. Let us know what you find out.. By the way where are you in S. Florida??
