Engine  
Cover  
1. Remove the hex bolt on top of the engine cover (remove  
two hex bolts on the top of the cover on the DHT engine  
model) and slide the cover off (see Figure 9). Disconnect the  
spark plug cap, and remove any dirt from around the spark  
plug area. Remove the spark plug with a 5/8-inch spark plug  
wrench (see Figure 10).  
2. Inspect the spark plug. Replace it if damaged or badly  
fouled, if the sealing washer is in poor condition, or if the  
electrode is worn. Measure the spark plug electrode gap with  
a wire-type gauge. For good performance, the spark plug  
must be properly gapped and free of deposits. Correct the  
gap, if necessary, by carefully bending the side electrode. Gap  
should be: 0.60 0.70 mm (0.024 0.028 in)  
3. Install the spark plug carefully, by hand, to avoid cross-  
threading. After the spark plug is seated, tighten with a  
5/8-inch spark plug wrench to compress the sealing washer.  
When installing a new spark plug, tighten 1/2 turn after the  
spark plug seats to compress the washer.  
Figure 9  
4. When reinstalling the original spark plug, tighten 1/8 -  
1/4 turn after the spark plug seats to compress the washer.  
A loose spark plug can overheat and damage the engine.  
Overtightening the spark plug can damage the threads in  
the cylinder head.
