The SV is overheating. There´s plenty of water in the radiator, but I overfilled the oil and since doing this it´s started overheating. I´ve drained off the oil, so it´s now at the correct levels. Also, there seems to be a hose missing (guessing). Front cylinder top side of cylinder as you look from gearbox side. There´s nothing I can see that the pipe sticking out of the cylinder connects to , and there´s no dangly hose anywhere, but I bet it may have something to do with tyhe cooling system ? Please help
