There is no powervalve leak of any consequence in 92-96 .CR 250 s

While the engine is running 1 psi drop in 6 minutes is nothing.The engine is running at 1000 s of rotations per minute.

Also the engine tolerances will tighten up once the bike gets up to temperature.

The main consideration is for the valve assembly to be free of stiction.
Rubber o-rings, seals-goop whatever=drag.
