Refer to Maintenance Scheduling → Regular Service Intervals → Regular Service Intervals: 2005 VRSC Models. Check the spark plugs at proper mileage intervals.
CAUTIONDo NOT pull on any electrical wires. Pulling on electrical wires may damage the internal conductor causing high resistance, which may result in minor or moderate injury. (00168a)
Before installing spark plugs, the gap should be checked and adjusted if necessary to 0.035 in. (0.89 mm).
Be sure your motorcycle has the correct spark plug. Use a 10R12A spark plug.
Spark plugs must be tightened to the torque specified for proper heat transfer. Tighten spark plugs to 23 N·m (17 ft-lbs) per spark plug.
NOTE
- If a torque wrench is not available, tighten the spark plugs finger tight; then tighten an additional one quarter turn with a spark plug wrench.
- The VRSC is equipped with plug-top coils. To inspect the spark plugs, the coils must be removed. Consult the VRSC Service Manual for the proper service procedure.
