If you complete a compression test on a cold engine, the reading will be inaccurate.
How To Do A Compression Test (Dry) Start with a warm engine, the ignition and fuel disabled, and all spark plugs removed. Above all, wear protective clothing and gloves, while working around a hot engine. While doing the test, the throttle and choke plates, must be fully open, for an accurate test. 03 Road King compression test Can someone tell me if the hollow bolts connecting the air filter to the cylinders have anything to do with compression readings.

Ice pack or cold compress If you test the compression with the engine cold you will get a good enough reading. If you test it warm it should be about the same. That is the running compression. Most motors that have a hard time starting when they are warm is because the compression is too low. Worn rings is the main cause of this.
The leak down test and compression test are both diagnostic tools used to assess the condition of an engine’s internal components. The leak down test measures the percentage of pressure loss in each cylinder, indicating potential leaks or worn piston rings, while the compression test measures the maximum pressure achieved during the compression .
Re: What can you learn from a COLD engine compression test. Last time I did mine it was@105 cold and then I warmed it up and got @145 so on a cold motor you will still want at least 90-100.

The test is to determine if a low compression is due to poor ring or poor valve seal, and the latter is clearly the case in bore 2. No significant change in pressure, so a bad valve seal.Learn what weather-specific features to look for when purchasing your gear.
