Major service on ZRX is worth every cent of that. It is an all day job to do properly. To get valve cover off fuel tank, radiator and top hoses must come off then of course reinstalled after valve adjustment. Reinstall coolant and bleed at two places- water pump and thermostat. All time consuming and other tasks also, I have two ZRXes and sometimes their services fall due at the same time. Yay!
