As said check methodically complete cooling system. The idea of pressurising raises the boiling point of coolant. Dont assume the worst. It is common for exhaust to appear "white" on start up-this is only water vapour & poss some unburnt fuel. The rubber seal on your pressure cap looks past its best in the photo so maybe replace that for starters.. Check each hose & jubilee clip in system. Also drain hole @ base of oil cooler lower front of engine as mentioned. Dont know if theres a coolant drain screw on lower hose (there is on Fazer thou)-if so check for leaks here as well. Once youre happy no leaks-flush system thoroughly-easier to remove rad to do this?. Drain & fill with proper motorcycle coolant eg Motul/Castrol whatever. Run engine up to temperature & keep an eye on level of coolant in rad/reservoir. good luck :lol
