My 2007 MV Agusta F4 1000R has really suffered in the summer’s heat. It has always run hot at about 110 degrees, but it started to boil up and got to 125 degrees, which is when I switched it off in a hurry. I let it cool down and it fired up again, but the reading was soon climbing into the “danger zone”. What can I do to sort it out?

You can get hold of a bigger impeller with five blades and a larger water pump housing for about £200. Out in Iraq they use straight anti-freeze in the Hummers to cope with the Middle East temperatures, but you’d be better of refilling it with a 60/40 mix of anti-freeze and water as that will raise the boiling point of the coolant sufficiently for our summer climate.
