Fuel System (CRF250R)
44 Servicing Your Honda
Fuel System (CRF250R)
Refer to Important Safety Precautions on page 23.
Use only unleaded fuel in your CRF. If you ride
your CRF in a country where leaded fuel might be
available, take precautions to use only unleaded
fuel.
Your engine is designed to use any unleaded
gasoline that has a pump octane number of 91 or
higher. Gasoline pumps at service stations
normally display the pump octane number.
For information on the use of Oxygenated Fuels,
see page 179.
Use of lower octane gasoline can cause persistent
“pinging” or “spark knock” (a louder rapping
noise) which, if severe, can lead to engine damage.
(Light pinging experienced while operating under
a heavy load, such as climbing a hill, is no cause
for concern.)
If pinging or spark knock occurs at a steady engine
speed under normal load, change brands of
gasoline. If pinging or spark knock persists,
consult your dealer.
Never use stale or contaminated gasoline. Avoid
getting dirt, dust or water in the fuel tank.
1. To open the fuel fill cap (1), pull the breather
tube (2) out of the steering stem nut (3). Turn
the fuel fill cap counterclockwise and remove
it.
2. Add fuel until the level reaches the bottom of
the filler neck (4).
Fuel Tank Capacity: 1.66 US gal (6.3 ℓ)
• Be careful not to damage the fuel pump while
filling the fuel tank.
• Avoid overfilling the tank. There should be no
fuel in the filler neck.
3. Close the fuel fill cap and insert the breather
tube in the steering stem nut.
1. Hang the fuel tank to the left side of the frame
(page 34).
2. Remove the fuel quick connect fitting cover

deterioration, damage or leakage. Replace the
fuel line, if necessary.
