[Retarding the engine.]

To retard the timming, you need to rotate de plate same direction flywheel rotates.

Flywheel nut is veery tight. You will need a impact wrench. Mark nut and axle with a chisel. So, you will know how much you should tighten on reasembly to keep same tension.

Lack of torque in this nut can cause sheared key

[Montesa 4ride or equivalent?]

You need a TRS X track

[Too Much Gearbox Oil?]

The oil my ST had less drag was with motul transoil.

 

[What kind of clutch oil should I use?]

In fact it is not the cap that is green. The rubber under the cap that is green when mineral oil is used. (Mostly)

You can double check with a drop in water:

1 dot oil mix well with water and turn white.

2 mineral oil floats

Seems ok to me.

If it is normal, sound should keep average the same as time goes

If there a problem, it probably will get worst and worst.

So, give bike a good ride, have fun and hope everything will be fine

[Please help, 290 crank nut remove]

Mark the nut and axle relative position first.

Than remove nut with a impact gun

Change seal

Reinstall nut with impact gun untill marks realign again.

This way proper tigtening is garanted

I'm wondering if as I've got new pads and disc whether it just needs to bed in, or if the pads could be ruined as there was a lot of brake fluid getting spilt!

.....

Yes.

Remove pads, clean disc as best as you can. Sand pads. mount again
