Ok, soo... This is the Situation, I think I have narrowed it down to a couple of Possibilities. Basically - A head gasket or a Cracked head. So I top the Radiator up to full ( the Bottle has correct Level ) The bike runs Beautifully, Go out for a "Decent" ride around Semi city/Rural for 45min - 1hr by the time the hour is up the bike is Running Close to hot, Get home let it cool down and it's used about 300ML of Water. Enough to heat the engine up. So, ive looked for Leaks there are none, nothing coming out of the exhaust etc. Considered a few things, - Blocked hose between radiator and bottle - Thermostat stuck open or Closed - Cracked head - Blown Head gasket ( unlikely but possible ) before I start Stripping the bike to find a solution thought i'd get some more Opinions.
