There's a very small window of opportunity to get the rings to seal really well ... the first 20 miles !!

Once that happens there is no solution but to re hone the cylinders, install new rings and start over again.

An excellent point also! Especially in two strokes, seating the rings is critical and happens quickly. "They" (who is "they" really?) also say to decelerate from higher RPM's when slowing down and use your brakes less. This creates vacuum in the cylinder to expand the rings. This helps with seating.
