Compression ratio calculator: Compression Ratio to PSI Calculator - Calculator Academy I just ran a compression test on my 2011 KTM 150XC and got just shy of 100psi. I did the test with the engine warm, three kicks with the throttle WO. The first kick would usually give me ~50-60 psi the second would bring me to 70-80 psi and the third would give me 90-100psi. The bike has 53. As for testing the compression, warm the engine, ground the spark plug wire to the frame.

Make sure its on or the bike will run like krapola.

Poor a little 2 Stroke in the Cylinder. It will work its way around. Do a compression test after that. If it goes up to normal numbers. Cylinder wall or bad ring seating. Answer the questions above. If the numbers stay relatively the same. Then it might be a guage. Make sure you are holding the throttle wide open when kicking.
