I replaced my cylinder head awhile ago on a sm with a e head with e cams aswell, now i have coolant overflowing constantly from the expansion, so bad even, my left leg was covered in the green. I am trying to work out why this is, i am thinking maybe i should take the thermostat off i really don't know. Also the head itself gets very hot, overly hot i would say, aswell as the oil filter case the stator caseing side even the clutch case was quite hot. I think tho the oil filter stator and clutch caseings have stopped getting so hot but i really haven't been able to run the bike for a long time to test it out fully. Any ideas ?
