Thanks for all of the welcome messages, I have got the bike running after flushing the cooling system and stripping the carbs. Water pump and cam belt look good so the next step is to overhaul the clutch hydraulics and take the old girl for a ride.
I'm going to replace the carb insulators as they are hard and old and unfortunately I will need to replace the intake tubes as the last visitor to this area had no idea!!!! parts supply at the moment is not good as Honda has stopped airfreight from Japan to Oz.
Engine runs well considering no sync or mixture adjust yet. 200,000 k's and no noise or smoke to worry about.
I have no idea of the history on this bike so I'm taking the cautious approach. Tyres are Metzeler from 2013.
I will flush the cooling system again and use type 2 coolant once I have replaced the thermostat, hoses and rad cap back to original.
I'm now looking at grips so things are moving forward!
Keep Safe
