Remove cams and they are only held in with a circlip. Once its been removed slide off the thinner gear along with the spring and locating dowels.

Did the same with my engine.
you need to remove parts; 9, 10, 11 and 26, 27, 29

But it would be worth doing the shims while you have the engine out

The loss'es you get from the lower gears is minimal, now they are not attached at the cams.
EDIT: Just leave them in place

Good point, but does the bottom one really need to be removed? I left them in as they wont mesh into anything so will not add any drag to the motor if that makes sense?

Edit, You beet me to it mate

Do you have to shim up the cam drive sprocket then to stop it moving on the cam??

I never shimmed/adjusted anything. All seems to be fine

I didn't with mine, it's a pretty snug fit so there shouldn'y be to much movement.
It does make it sound like a bag of spanners compared to having them in though.

You beat me to it this time
We need to have some buzzers, like they have on a game show

You left them in think about all that weight that could be saved

But still will be looking in to this because I like the noise it makes

Mine used to pass noise tests until i removed them, now it sounds like its trying to eat itself
