The bowls are machined slightly off centre.
Centifugal force tends to keep the bowl upright when running at speed but as it slows down and falls to the side due to the off centre machining the bowl tends to curve more.
There are no weights used to effect a bias and it is unlikely that you can manufacture a set, and the cost of getting them tested for legal use would out weigh the savings of making yourself a set.
The A to Zen of Lawn Bowls by Salter and Bliss has a chapter dealing with the mathematics of how and why a bowl does what it does in motion
