Yes , the bearings need lubrication.
And i am thinking about a twin-screw blower....

Does anyone know of a supercharger that fits a two stroke 50cc engine?
Any recomendations?

On two strokes oil are pre-mixed in the fuel, to lubricate the engine.
The oil-fuel mixture usually passes from the carb and in to the
cranc-case,
and then to the cylinder.

I dont like the idea of having to mount a external oil pump and plumbing
to
lubricate the supercharger.

I found this project while surfing on the net.
It is a supercharged 4-stroke Honda CD50.

Are you talking about bearing lubrication? There are plenty of
supercharger designs that have self contained bearing lubrication.
