“Stripping the Engine

In the first of our new series, John Wyatt – armed with tubs and plastic bags – shows us how to take the vee-twin CX500 engine apart.

Remove the transfer pipes, the thermostat housing and air spoiler plate from the top of the engine. Note the ‘O’ rings.

Working on one cylinder at a time (in order to keep parts separate) and having some plastic bags or equivalent at the ready, undo the two chrome bolts on the rocker cover, inspecting the rubber gaskets underneath.
