For lower bearing, best find someone with a press. It need 3 to 6 ton to move. See process here:

Or you can cut the bearing with a dremel. Be carefull to not damage the stem

Or you can weld some scrap metal to the beaging race and hammer it while hot. 

Any method, take care of the threads on stem.

Outer races go out easily with a long chisel.

This practice (removing bearing with a drift off center) move bearing crocked what on long therm enlarge hub diameter.

Jitsie make a wheel bearing extractor that solve this issue and is able to remove Rear wheel bearing since spacer id is smaller than bearing id.

 

If your scorpa has tech forks: 

 

This spark plug look too white (learn) for me. Brown ir the gold spot.

Had this spark plug for how long? If you rode few hours with this one, you need bigger jets. 

Mechanix gloves work too

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

You need a TRS X track

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

 

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

If you know nothing about motorcycles, go to the less risk and buy the newer.

Main plug failture root cause is rich carb

Bought from parker store downtown.

Others seal and hydraulic gasket stories can have these seals too.

 

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

No misteries rebuilding these standard shocks

 

Kerosene is greath for filter cleaning

Had you looked at dremel 90 degree attachment?

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

there was some rumors about aluminium frame....

 

This weight is a personal preference and you can experiment what work better
