      I have a weird problem on my dt. The coolant is going back to the expansion bottle and it gets filled up and leaks out, and when i open the radiator and rev the bike it spits out water. Ive tried two heads, and swapped headgaskets. Changed the bearing with the water pump. What could cause this?

        @Bananper Is the water pump performing correctly or maybe a blocked pipe perhaps???

            @Bananper In the correct direction? I'd check the pipes next then, if all is well then what has changed to create this problem, or has it just occurred on it's own???

              @NINJA i swapped the whole engine. There has always been something wrong with the cooling system in one way or another ever since

                If it's going into the expan then it's leaking past the cap. Try a new cap 1.1 bar

                  @Louis-James yeah but it should not be that much pressure

                    Your cylinder gasket surface might not be good, or your nuts not torqued enough

                      When i took of my cylinder head i could see the piston had water on top, and i pulled of the cylinder and the cylinder gasket was really blown. Water everywhere on the piston but no major damage

                        Might sound silly but you are using a genuine head gasket or an Athena one yes?
