Piston Height Measuring Tool – 250 cc Engines (Dial Indicator Not Included)

The VHM AM34014 piston height measuring tool is designed to allow precision measurement of piston height in performance 250 cc engines when fitting VHM cylinder heads and inserts. Correct piston height is critical to ensure proper squish clearance and combustion chamber volume. The tool includes an upper measuring part and a lower calibration part; you start with the lower part for calibration then use the upper part on the cylinder to measure piston height. The dial indicator is not included and must be purchased separately. This tool simplifies one of the most critical tuning steps—ensuring correct deck height alignment and thereby optimizing engine performance and reliability.
