US PRO 6945 TDC Dial Indicator Gauge for Motorcycle Ignition Adjustment

Accurate ignition timing starts with knowing exactly where top dead centre really is, not where you think it might be. The US PRO 6945 TDC Dial Indicator Gauge is built to give that certainty when setting up motorcycle engines, whether for routine servicing, tuning, or performance work.

This precision gauge allows you to locate the exact top dead centre position of the piston by measuring true piston movement rather than relying on timing marks alone. Supplied with both 10mm and 14mm spark plug adaptors, it suits most common motorcycle cylinder heads. The included adaptor extensions and probe tips provide flexibility across different combustion chamber designs and access depths.

Housed in a protective storage case, this kit is ideal for workshops, engine builders, and serious motorcycle enthusiasts who demand repeatable accuracy when adjusting ignition timing.
