Frequently Asked Questions - CRF80F (2011) Honda
What type of oil does the Honda CRF80F (2011) use?
The recommended oil is 10W-30 or 10W-40 motorcycle oil, API service classification SG or higher, and JASO MA standard. Use approximately 0.6 L (0.63 qt) with filter change.
How do I start the CRF80F?
Ensure the fuel valve is ON, the choke is pulled out (for cold start), and the transmission is in neutral. Pull the decompression lever (if equipped) while kicking the kickstarter firmly. For a warm engine, do not use the choke.
What type of spark plug does it use?
The correct spark plug is NGK CR6HSA or equivalent. The gap should be set to 0.6–0.7 mm (0.024–0.028 in).
How often should I change the oil?
It is recommended to change the engine oil every 600 miles (1000 km) or every 6 months, whichever comes first. More frequent changes are advised if ridden in severe conditions.
What is the correct tire pressure for the CRF80F?
For off-road riding, the recommended tire pressure is 15 psi (103 kPa) front and rear. Adjust for terrain and rider weight.
How do I adjust the chain slack?
The chain slack should be 25–35 mm (1.0–1.4 in) at the middle of the chain run. Loosen the rear axle nut and adjust the chain adjusters equally on both sides, then retighten the axle nut to the specified torque.
What is the fuel type required?
Use unleaded gasoline with a research octane number (RON) of 91 or higher. Avoid using ethanol blends above 10% (E10).
How do I clean the air filter?
Remove the air filter element and clean it with a non-flammable solvent or soapy water. Allow to dry completely. Then apply foam air filter oil evenly, squeeze out excess, and reinstall. Replace if damaged.
What is the break-in procedure for a new CRF80F?
For the first 600 miles (1000 km), avoid prolonged full-throttle operation and vary engine speed. Do not exceed 3/4 throttle. After break-in, check and tighten bolts, adjust chain, and change oil.
Why won't my CRF80F start?
Check the following: fuel valve ON, enough fuel, spark plug firing (clean and gapped), air filter clean, choke used correctly, and the kill switch in the RUN position. Also check for a clogged carburetor or weak spark.
