What did I forget to check? Replaced radiator cap, flushed radiator, installed new water pump, set timing to specs in manual with dial indicator, changed cylinder head and head gasket, ran with no thermostat also tried running with a different thermostat and still overheating within a 10 min ride time. Pushes coolant out of overflow when overheating.
Could the cylinder jug be having issues?
P.S.
Running 30/1 oil ratio

Sometimes if there is too much water it will blow out the excess. Does the red light come on also to indicate overheating or just coolant coming out overflow tube. After it over heats is there still coolant in the bottle under the seat?

yes the light comes on.Also I was thinking about it, since i just bought this one, I'm going out to check the jets in the carb to see what they are. Maybe the other owner changed things on it.

Does it have the oem carb? You can check it against the oem jets if so. They should not be smaller. Check the color of the end of the plug and see if its sorta dark or light colored.
That would cause it to run hot. Too lean. Also make sure the water pump is good and not slipping on the shaft which is a common problem.

Assuming its good check the jets and you may need to run with out a thermo for a bit. I think some guys run with out one without problems. Just got to keep eliminating potential causes to you find it. Make sure all of the vent tubes are clear and don't have dirt or bugs hid inside.

Would the crank seal do this? No oil visible on the stator side when i had the cover off to set timing

I don't know. I believe that would cause loss of some of the compression but not sure if it would cause it to overheat.

ok just checked the main jet, its a 470 and i checked my other tri-z's and they all have 470 jets in them also. MTS its doggy, trying to catch up but sometimes it runs great. but then sometimes it surges on idle up and down then can take it for another spin then it will idle fine. haven't checked the plug yet.

Check your intake for cracks and a good seal on your boost bottle tube, make sure all your motor mounts are tight also..a moving engine wrecks havoic on the intake system of a tri z.., sounds like a air leak somewhere to me.
