Spark Plug

The spark plug should be taken out periodically for inspection and recapping. Measure the gap with a wire-type thickness gauge. If incorrect, adjust the gap to the specified value by bending the outer electrode.

Spark Plug Gap

• NGK R6252K-105.0.8 mm (0.028~0.031 in.)
• NGK BR9EVX 0.6 0.7 mm (0.024 0.028 in.)
