    My Tecate did that after the rebuild. I got a bad head gasket. It happens sometimes. Make sure you use the best brand for your hot rod (Yamaha?).
    83' 200x (son's). 85' 200 auto-x & 85' 125m (daughters). 84' Tecate(?). 85' KXT Tecate (mine!, mine!, mine!.)+ some others but don't feel like typing them in.

    I have also had that problem with a ATC 250 R. Turned out to be a warped head...
