Hi,
Bike shops, as in: push bikes with pedals, sell loose ball
bearings.
I thought, but it’s a while since I’ve built GS
150, that these bearings are the same as all large frame Vespas? If that’s
the case, the caged variety will fit.
Failing that being the case, just assemble the race with as many
balls as will fit, using grease as an adhesive. This is the reason why
the actual number of balls per bearing is not well known no one ever counted
them. This is standard bicycle workshop practice.
Incidently, it was a little known tip used by racing scooterists
to dispense with the caged variety of races to allow more balls to be fitted
and to improve the level of contact of the balls in their tracks. The
cage just makes fitting a bit quicker, as it happens.

I believe there should be 19, it's an 8mm diam
ball. If you are in the UK Allstyles do a set in a cage to make it easier to
fit, Bill Drake supplies them loose, got to tackle mine before long..

in there, as I'm sure the previous owner must have lost a few (this bike has
been a apart a few times it seems). Where would be a good place to source a new
set?
