Common questions
What does a leakdown test actually measure?
It measures how much combustion pressure leaks past the rings, valves, and gaskets — revealing wear that compression tests alone can't detect. This helps pinpoint the exact source of compression loss.
Do I need special air pressure to run this kit?
Yes, you will need a shop air compressor. The kit includes an adjustable pressure regulator, and you'll set your compressor to the recommended pressure shown on the gauge during testing.
Will this kit work on my specific Harley-Davidson or Indian Motorcycle?
This kit fits all V-twin motorcycles, including Harley-Davidson and Indian Motorcycle models, that use standard 10 mm, 12 mm, or 14 mm spark plug configurations. Confirm your spark plug size before ordering.
