I ran a compression test on my bike and its about 40. I just need to know what it is supposed to be. KTM 300mx (2-stroke).

how many kicks / strokes did you do to get the 40???
minimum 125 psi (time for a top end then) ...
proper pressure after 5 kicks should be in the 175-190 psi range on fresh top end for that bike.
make sure to either push the kill button or ground the plug to the engine while kicking it over, or you could damage your CDI unit...

Your engine is shot.
Time for a rebuild.
2 strokes need at least 125psi

With the throttle open give it four kicks, comp should be around 125psi. PMK what on earth are you talking about?
