. Check the condition of the spark plug once the motorcycle has done 1000 km. Remove encrusted carbon deposits and check the gap between the two
electrodes, which should usually be between 0.7 and 0.8 mm. The spark plug has a service life of 5000 km.
12
. How to use the clutch
Do not ride with the clutch pulled only part of the way! This can result in excessive wear to the clutch assembly, making it slip, or at least burn.
Clutch noise should be constant and consistent with engine idling. You may notice a bit of clutch noise when starting / switching off the vehicle.
The sound disappears as soon as engine speed stabilizes.
13
. Maintenance:
A
. Change oil every 5,000 km following the run-in period. Change oil before it starts to deteriorate. Check oil level before each ride. Fill the crankcase with
lubricant when the oil level drops below the bottom line on the sight glass.
B
. Check coolant level before each ride. Open the radiator cap to check whether there is enough coolant inside the radiator or not. If there isn't, top up as
required and restart the engine. A good antifreeze must be used over winter to stop the water freezing.
C
. Check and adjust valve clearance. Generally speaking, valve clearance is factory set before delivery.
Adjust values when something unusual happens: 0.05 mm to 0.07 mm.
D
. Carburettor cleaning: clean the carburettor by dismantling it completely following evident trouble with engine power delivery, or when it is not running
evenly. Remove the carburettor from the motorcycle before cleaning the outside. Take it apart, part by part, and clean all parts one by one, washing
them with petrol and blowing compressed air inside all petrol and air channels. During removal and disassembly, do not touch the float arm, the float
arm pin and other positions.
E
.
Air filter: clean or replace the air filter every 1000 km. Inspect all the air filter's mating surfaces for airtightness to ensure air enters the cylinder through
the air cleaner only. Keep the air filter clean as this is where dust stops and builds up.
F
. Clean the spark plug: clean and adjust the spark plug every 1000 km. Leave the spark plug to soak in petrol for 3-4 hours to soften the carbon deposits,
which you should then remove with a scraper. Brush the spark plug with petrol and dry it. The spark plug must be replaced at regular intervals per the
owner's manual.
G
. Inspect all bolts and tighten any that have come loose.
H
.
Clean and check the oil filter and screens every 1000 km.
(1)
Replace them in good time if they are damaged;
(2)
Cleaning method
A
. Cleaning filter screens: remove the filter screen caps from the left and right crankcases and remove the filters with needle-nose pliers; wash the screens
with clean petrol to remove all impurities; refit them in their slots and screw the fastening caps back on. Tighten the filter screen caps to a torque of
between 11 and 13N · m.
B
. Cleaning the oil filter: remove the 2 nuts and remove the oil filter cap with a screwdriver. Remove the fine oil filter parts and wash them with clean petrol
to remove all impurities; once clean, refit it in its slot. Make extra sure you refit the filter with the opening facing out from the engine before fastening it
in place with its cap. Tighten the 2 nuts to a torque of between 7 and 9N · m. When riding in challenging conditions, the filter cleaning interval should
be reduced accordingly. The clean oil filter screen can be reused. Make sure you check the oil level following inspection and cleaning. If oil level has
dropped below the bottom line marked on the sight glass, idle the engine for 20 seconds and check the oil level again. If oil level is still below the
bottom line marked on the sight glass, add oil.
Note
: refit the filter with the opening facing out from the engine
