My 2001 gsr has 240/cylinder, 140 seems low, was it 140 dry or wet?. If you want best results make sure your engine is as warm as possible, make sure your at wide open throttle. For a wet test, pour two table spoons of motoroil through each spark plug hole (one at a time) and repeat the test. If your results increase, your rings are worn since the oil itself is over-sealing the oversized clearence between the ring edge from the cylinder wall, due to worn rings.

he is talking about the b17, not the b18c1.

that is low. minimum is 135. max should be around 184. variation should be 28.

though it is low, it still is drivable. i bet it drives like crap.

leakdown to isolate the problem.

consider your options after that.

swap or rebuild.

smoking on full throttle means the rings are goin on ya!

My 99 GSR has ~210 per cylinder i think it was....
