As said, dont be daunted by 'dropping the lump'
One of the reasons I, and I suspect many others, stick with a CX is
they're so easy to work on.
From memory:
Seat off, tank off, put away safe
drain oil and coolant, examine oil and possibly filter for particles
remove exhaust
Disconnect plug leads and electrical connections to engine
Working backwards, remove inlet manifolds ( bolts twist and pull off) then carbs , leave airbox rubbers in place
remove 2 8mm headed bolts at rear of starter
use a screwdriver to gently tease the thing out the case then turn it towards yourelf to remove the
10mm headed nut and cable.
While your there, stick a finger in the hole and try pushing the starter ring about
It should go downwards easily but lock as soon as you try and push it upwards
If it doesnt keep this in mind when its opened up.
PUll the rubber boot back and remove the 12mm headed long bolt that holds the drive shaft in place
then ease the shaft off the motor
SUpport motor, remove bolts and its out !
I find a trollay jack very useful and another pair of hands is nice and probably advised
when dropping and lifting the motor.
Rear cover:
Remove Water pump cover first then impellor
note and keep the small washer under the impellor safe
Remove Pulser cover then advance unit
Pulsers can stay in place
Once you've removed the bolts and cracked the case, open it carefully and dont drag the gearchange shaft
out with the cover, many of us have first time and its better to tap it back in gently as you pull the cover.
Take your time
Stop for tea biscuits, bacon butties etc whenever you feel the need
Take lots of pictures
