In my last post I covered what a leak down test is and how it can be used to determine engine problems. Today I’ll go through and detail how to do a leak down test on your dirt bike engine step-by-step.

How to Perform a Leak Down Test
To perform a leak down test you will need an air source capable of at least 115psi output pressure. Most leak down tests are performed at a regulated pressure of 100psi. This makes testing simple and the correlation of leakage a breeze since you’re working on a scale from 0-100. Lower test pressures such as 90psi can be used in the event that the air system isn’t capable of anything over 100psi or the specific leak down tester you have doesn’t work on a 100psi scale. Just remember if you test at a value other than 100psi, you will need to mathematically determine the leakage percentage since it is no longer a direct correlation. |
