200 psi
For a 1985 KX250, the recommended compression ratio is typically around 8.5:1 to 9.5:1. To achieve optimal performance, the engine should have a compression pressure of approximately 150-180 psi when tested with a compression gauge. It's essential to ensure that the engine is in good condition and has proper maintenance to achieve these compression values. If the compression is significantly lower, it may indicate wear or damage that needs to be addressed.
Normal compression on a gasoline engine is about 125 psi.
87 - 04 compression standard 121 psi minimum 114 psi max 128 psi
100 psi and all within 25%100 psi and all within 25%
then youre running about 8.5:1 compression

The compression ratio of a 2001 Kawasaki KX250 is approximately 8.5:1. This means that the air-fuel mixture in the cylinder is compressed to 8.5 times its original volume before ignition. Compression can vary slightly based on factors like engine condition and modifications, but this ratio is typical for that model. Regular maintenance and correct fuel can help maintain optimal compression levels.
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Engine compression psi? Radiator cap psi? Engine oil pressure psi? Tire pressure psi? Fuel pressure psi?
With a compression gauge.
Tire psi? Engine compression psi? Radiator cap psi? Engine oil pressure psi?
i did the math and the exct commpression is 183.75 psi
