Checking and Changing Spark Plugs (Cont'd)
MA-18prose procedureDistinct specifications for model with catalyzer (Platinum-tipped spark plugs: PFR6A-11 standard, PFR5A-11 hot, PFR7A-11 cold) versus model without catalyzer (Conventional spark plugs: BCPR6ES-11 standard, BCPR5ES-11 hot, BCPR7ES-11 cold). Gap check required only for non-catalyzer models.
ENGINE MAINTENANCE
Checking and Changing Spark Plugs (Cont'd)
- 2Disconnect harness connector between ignition coil and power transistor.
SMA996B - 3Remove ignition coil bracket fixing bolts and pull out this bracket with ignition coils.
- 4Remove spark plugs with suitable spark plug wrench.

NOTE
Checking and adjusting plug gap are not required between renewals.
Never use a wire brush for cleaning.
If plug tip is covered with carbon, spark plug cleaner can be used.
