WARNING
When the engine has been running, the exhaust muffler is very hot and dangerously hot to the
touch.
2. Check the spark plug visually. If there are signs of wear around it or the gasket is cracked, replace
it with a new one. Before reinstalling a spark plug, clean it with a wire brush.
3. Measure the spark plug gap with a feeler gauge and adjust it by bending the side electrode. The
spark plug clearance should be 0.70-0.80mm.
4. Check that the spark plug gasket is in good condition or replace it with a new one. Drive it into the
engine with a spark plug wrench to protect the thread from being damaged.
Note
: When installing a new spark plug, after it touches and presses the gasket, twist a half turn; for a
used spark plug, twist 1/8-1/4 turn.
