INSPECTING THE SPARK PLUG
If in doubt concerning the condition of the spark plug,
consult an authorized Cannondale Motorsports dealer. The
simple answer is to replace an old spark plug with a new
one anytime you remove it, but since the spark plug is a
valuable indicator of engine operating characteristics it is
extremely important to have it evaluated by a skilled service
technician. Consult an authorized Cannondale motorsports
dealer.
The spark plug gap (a) must be measured with a wire gauge
or feeler gauge. If the gap is out of specification, adjust it.
If the spark plug utilizes multiple ground electrodes,
measure each gap.
INSTALLING THE SPARK PLUG
CAUTION
Only install the spark plug into a cool engine.
Always use the specified spark plug with the proper
gap. Using an incorrect spark plug may cause
severe engine damage.
Incorrectly installing the spark plug can damage the
cylinder head. An overly-tight or cross-threaded
spark plug will damage the threads in the spark plug
hole
Make sure the specified gap is set and lightly coat the plug
threads with a suitable anti-seize compound; this will allow
for easier spark plug removal in the future.
Then, finger-tighten (a) the spark plug into its hole, and
tighten it to the specified torque (b).
