Morning all, I can't seem to get my 1985 250r running right, this is my second time replacing the head gasket. The reason I replaced it the first time is because it was overheating and the coolant was bubbling, after removing the top end there was coolant in the crankcase which led me to believe the head gasket was blown. After replacing the head gasket for a second time, it started on second kick and I got about 1-2 min of good run time, then with the radiator cap off while it was running briefly, it sucked down coolant and then started running really rough and then it stalled out. Attempting to kick start it after it stalled, it shot coolant out of the radiator. After removing the top end for a second time now, there is coolant in the crankcase again.
Before all of this, I replaced the head gasket and torqued it back down to spec, a compression and a leak down test was performed both times. Leak down passed fine both times. Compression is at 176-180 both times. Cylinder was bored about 10 hours ago and it looks great and smooth and replaced with wiseco piston. Crankshaft is solid, no up and down movement. First time the head gasket was replaced it was replaced with oem metal head gasket, second time it was replaced it was replaced with tusk metal head gasket. Cylinder head has very low hours on it, but I did check it and it is flat with no gaps at all.
I also replaced the water pump impeller with new seals and gaskets. Radiator was cleaned out to ensure nothing is in the way. New radiator cap as well.
Not sure where else to go here. Any ideas would be appreciated.
