Any idea which is the suitable free-wheeling sprocket for this
"Standard Scooter Transmission w/20-Tooth (8mm 05T) Chain Sprocket"?

Would any of these fit? http://electricscooterparts.com/sprockets.html#BikeSprockets

Staton seems to have a goodly number of small freewheeling sprockets

Do any of them seem suitable?

I have a tranny similar to that one on the J-Dog. I have never looked into adding a freewheel because its a centrifugal clutch.

I Use That Gear Box (a Tuff Unit) On My Shifter. How Are You Planning On Using It?? There Is Not A Freewheel Available For That Shaft That I Know Of. Remember, It Reverses Rotation! There Are Several Ways To Have A Freewheel In The Sprocket That It Drives.

Mine had a reasonable amount of gear grease on the gears.

Does it need gear oil as well?

I USE HEAVY GEAR "OIL". A SMALL TUBE FOR OUTBOARD MOTOR LOWER UNITS CAN BE FOUND AND USED. MAYBE, EVEN CHAINSAW BAR OIL COULD WORK.

I WOULD NOT TRUST REGULAR HEAVY GREASE TO GET INTO THE BALL BEARINGS.

IT IS A WELL BUILT GEAR BOX. CHECK YOUR CLUTCH DRUM FOR WOBBLE, THAT COULD CAUSE DAMAGE.

ABOUT 1/2 FULL. IF THE VENT IS ON THE SIDE THAT SHOULD BE FINE. THE GEAR BOS CAN BE MOUNTED IN ANY POSITION. BUT THEN YOU MAY HAVE TO MODIFY FOR VENTING, WITH OUT A VENT IT MAY BLOW THE SEALS OUT.
