14.2 VEHICLE OPERATION AND MAINTENANCE ON CARBURETTOR VERSION
1
. Check the oil level. When the average oil level drops below the bottom line marked on the sight glass, add lubricating oil.
2
. Nominal weight: it is recommended that nominal weight not exceed 150 kg
3
. Starting:
A
. Start the engine (using the electric starter) with the bike in neutral. Do not start the engine with the bike in any gear. This can cause mechanical damage
(damage to the clutch, etc.) and personal injury.
B
. Pull the choke when the engine is cold.
Skip this step if the engine is warm.
C
. To start the engine over winter, follow the cold engine starting procedure described above. Leave the engine idling for 3 to 5 minutes and do not put it
into gear until the engine has had time to warm up.
4
. Keep the engine idling for 3/5 seconds after starting the engine. Do not run the engine at high revs and speeds until it has had time to warm up. Do not keep
the clutch pulled half way for any length of time. This results in premature, abnormal clutch wear.
5
. It is very important to run-in the engine. Under no circumstances should you use the bike at full throttle until it has done 500 km. Maintenance must be carried
out when the bike has reached 500 km. Check and adjust valve clearance, and clutch disengagement; clean the oil filter screens and check that the fine filter is
clean, installing a new one where necessary, to keep the engine in proper working order.
6
. Check the cylinder bolt tightening torque once the run-in period is over. For engine NC 250, the M10 bolts must be tightened to a torque in the 55 to 60 N · m
range. Inspect the spark plug when the bike has done 2000 km. Clean the electrodes of carbon deposits and check the gap between them, which should usually
be between 0.7 and 0.8 mm. The spark plug has a service life of 5000 km.
7
. Lubricating oil change procedure
Change the lubricating oil when the bike has done 500 km. The lubricating oil brand must match that provided by the manufacturer. Do not use lubricating oil
of poorer quality.
Oil change procedure:
A
. Remove the cap from both oil filter screens on the left and right. Remove the filter screen with needle-nose pliers and remove the drain cap.
Give the oil a few minutes to drain out of the engine completely.
B
. Fit the filter screens on both sides and fasten them in place with the relevant caps. Tighten the cap to a torque of 11 to 13 N · m. Apply 3 - 4 drops of fluid
sealant to the drain cap, too, before fastening it and fit it on the relevant hole. Tighten the drain cap to a torque of 24 to 27Nm.
C
. Remove the oil filler cap from the right crankcase and pour in 1500 ml of lubricating oil, checking the level. Keep filling until the oil level reaches the
top mark on the sight glass. Lastly, refit the filler cap on the right crankcase and screw it on tightly.
8
. Adjusting idling speed
A
. Warm the engine up to its normal running temperature. Connect the rev counter and adjust idling speed to 1500 rpm by turning the fuel adjuster screw.
9
. How to use the electric starter
Only use the electric starter with the bike in neutral. Do not hold the electric start button down for more than 5s! This can damage the battery, engine, clutch and
gearbox. Note: check that the battery is sufficiently charged.
10
. Changing gears: never change gears with the clutch engaged and the throttle open! This can result in mechanical damage to the gears and drive chain, etc.
