Frequently Asked Questions

What spark-plug thread does compression tester 35-9031 use?

The flexible hose has a 14mm threaded end and the set also includes a universal adapter and quick coupling. Confirm the engine's spark-plug thread and sealing arrangement before installation.

How should a motorcycle compression test be performed consistently?

Follow the motorcycle service manual: use a charged battery, disable ignition and fuel, remove the required spark plugs, hold the throttle open and crank each cylinder for the same number of compression strokes.

What does a low compression reading prove?

A low reading shows a sealing or test-condition problem but does not identify the failed part by itself. Repeat the test consistently and use wet-compression or leakdown diagnosis to separate ring, valve and head-gasket causes.
