If you havn't had your brick long, and it was parked by the previous owner, just riding 1000miles could help. Also flush and replace the coolant, and a good service.
Check that there are no bubbles in the coolant and that the expansion tank level rises and falls, after and before a trip.
There should also be an infill panel to direct engine heat out the side vents, preventing it mixing with the fresh air vent. Seems funny, outside air vents on a motorbike.
