Piston Height Measuring Tool – 300 cc Engines (Dial Indicator Not Included)

The VHM AM34016 piston height measuring tool is designed to provide accurate and reliable measurement of piston height in 300 cc two‑stroke engines. Proper piston height is essential when fitting VHM cylinder heads and inserts, as incorrect height can adversely affect squish clearance, combustion volume and port timing. This tool comes with both an upper and lower part: the lower piece is used for calibration, and the upper piece is used for the actual measurement on the cylinder. The dial indicator is not included and must be purchased separately. With this tool, engine builders can ensure that the piston height is within the required tolerances to maintain optimum engine geometry and performance — ideal for high‑performance builds, inspections and tuning work.

Key Features / Benefits:

• Precision measuring tool designed for 300 cc engine‑capacity setups.
