Kymco Zing 125 - Popular Questions, Answers, Tips & Manuals

check the ground wire, some where not even connected and install a pig tale to the battery to charge it on the scooter, if the wires are OK you need a new stater check with kymcoforum.com and look up bet and lose

Change the bulbs on that side

the piston rings are fried

Hello ! Being an automatic shock, you can not manually interfere with it. If the shock is not working in the cold season, fault is the lack of power supply, or internal shock failure, more likely the thermistor pocket, creates problems by shortening it in most cases, or the connections of the slipper connectors etc. Check the presence of alternating voltage (12 volts) of power supply after starting the engine, with a small 12-volt bulb, or with a measuring device. With the engine off, disconnect the connectors, and with the Rx measuring instrument, also measure the thermal resistance of the thermistor, and the state of the contacts, you should find approximate 40-60 Ohms. Any deviation higher upwards or downwards, indicates a malfunction, and must be interfered with when it is removed. The construction shoe consists of a metallic capsule of the size of a cigarette filter, which at one end has a rod that comes in or out of the environment. At the other end is the thermistor, which is powered by a 2-wire the scooter's engine. This voltage heats the thermistor, which in turn heats the thermostatic capsule, it has an inertia to the piston's expansion, dictates the time for the heating of the engine, etc. at maximum cascade heating, rod relaxation will act and reduce excess gasoline, the engine entering normal speed. Hopefully, I was very helpful! Good luck

I found an owner's instruction manual on the net in Spanish that says:0,05 mm - 0,1 mmThis means that the valve clearance is 0.05 to 0.1 mm. A slightly tight adjustment using a 0.1 feeler gage should be ok and the real clearance would then probably be ca. 0.08 mm.

You should replace the fuel also as fuel deteriorates over time.Drain the tank and replace with new fuel.Also drain the carb.as it will still have old fuel in it.

pull the line off the caliper and pump the brake and see if fluid is getting to the caliper first.

Possibly, but that would be more likely to make it start easily and chuck black smoke out of the exhaust. Have you changed the spark plug? often the plug will work perfectly when sitting on the casing but fail when under compression in the cylinder. Is fuel DEFINITELY getting through?

It is good for invest cost but bad for quality.

It is a two stroke and has no engine oil as such because it is mixed with the petrol.

For your bike you should use 15w 40 oil. Buy some better known mark oil.

Some scooters seat latches operate with the ignition key switch.
Turn it left and right as you lift the seat.
Sometime you have to push down on the seat while you turn the key
Some have a key right on the left side of the bike for the seat latch.

If you have no key, you can pull off the rear rack and then take off the plastics above the tail light.
Once that plastic is off you can reach the latch with a screwdriver or needle nose pliers.

harness issue?i was an electrical sysems troubleshooter on planes.do any other switches do anything crazy?

Not always necessary to change the regulator/rectifier. Check all connections to make sure they are clean, use a good contact cleaner and finish off with dielectric grease on your electrical connections.
When some bikes get a few years on them the connections get dirty. Check to see if there are any burned or discolored wires anywhere around the regulator. The FIX on some bikes is to cut the connector completely out and solder the wires together and either seal them with heat shrink of a good electrical tape. Loose or bad connections get hot. As long as the regulator and rectifier are working there is no need to replace them if the connections are good.

Check the battery negative cable if its tightened well to the frame or the engine, check too, the fuse box and the main wire to the starter solenoid and the connections to the starter too, this sounds to be an electrical lose connection somewhere..just go along throught the wires and connections..
Hope this helps!

block your sender. but really this is the wrong place for this.

Most carbs are not adj, the jets are fixed in position, and in order to change fuel air mix, you have to change the jet. You could try high test gas, clean the air filter, get some hotter plugs in there. What is your elevation? All this will change the fuel/ air mix.

Hi, I'd check that one of the brakelight switches isn't stuck on, as if it's the park light it should put the front one on as well, some bikes have the headlight/taillight hardwired so come on with ign. on. The starter should have a fuse, check it, if ok, follow the main wires from the starter motor to the solinoid & check power's getting through with a test light (an old globe with a length of wire will do), the solinoid should have one large power cable to it from batt. with full time power, another the same going to starter that get's power when start button's pressed & a smaller one which should get power when start button's pressed (activates solinoid). if it is getting power to the starter when button's pressed, starter probably needs new brushes or just a good clean out, hope this helps.
