This is the main part of the engine, that mounts to the scooter body

Heres the picture of the main bit of the engine and gearbox, taken from the underside.  As you can see the piston and crank are still in place, but will need new bearings and seals.  Also certain gearbox parts too.

Here is an internal picture of the engine

As the photo shows this is a two port engine with all four gear wheels intact.  Later photos will show the cogs in better detail.
