MOTION PRO Leak Down Tester 08-0071

Diagnosing air leaks in 2-stroke engines requires precision—and guesswork will cost you power and reliability. The MOTION PRO Leak Down Tester gives you a definitive, repeatable way to pinpoint compression losses before they become catastrophic failures. Whether you're tuning a race engine or troubleshooting a performance build, this tool pays for itself the first time it saves you from a blown motor.

This U.S.-made tester includes everything needed for comprehensive leak-down diagnostics: an air pressure gauge for accurate readings, a pump-up bulb for consistent pressure application, and a full range of adapters to handle most 2-stroke configurations. The expandable rubber exhaust port plugs accommodate round ports from 35 mm to 60 mm in diameter, eliminating the need for multiple tools. All components pack neatly in a rugged carry box with detailed instructions, making field diagnostics or shop work straightforward.
