    What is considered low compression for a two-stroke.

    Specifically, a 50cc Suzuki JR50. I'm running 90psi and it starts easy, revs good, and idles okay (it's a two-stroke) but I've got no power at all. Can anyone say that "When compression falls below x psi, time for a fresh top-end." What's the threshold.

    anything under 70-80 psi, I always rebuild.
