It's not rocket science to be honest.

Look up the RC Valve page in the Online Parts Manual for a schematic of them.

Remove the expansion chambers and turn the crank so the piston is at TDC to stop the flaps from dropping into the cylinder!

Unscrew the RC pulley retaining nut (left hand thread) and pop the pulley off. You can leave the cables connected to the pulley.

Unbolt the RC Valve backplate and then extract the RC shaft. Easiest done with the correct Honda tool unless the valves are cleaned regularly (as they should be!).

With the backplate off there is nothing to hold the shaft in but carbon! There's an E-clip behind the oil seal which usually deforms as the shaft is extracted, but can be straightened. Removing the shaft normally damages the oil seal so it should be replaced when cleaning the assembly.

Again, if the valves are cleaned regularly it all comes apart very quickly and easily, without damaging the oil seal or E-clip.

In the best tradition of Haynes... "refitting is the reverse of removal"!
