My bike can't start few days ago, I managed to kick start it and ride to the nearest bike shop.. the Uncle say hard to say what problem, ask me change spark plug see how..

 

Change liao, ride 2 more days.. den i went to start my bike, can't start again.. Just now i managed to push start it, but after 10-20secs, the engine die off again..

 

What's the problem man?

Basics

Check fuel cock

Check Spark plug cap

Check petrol and 2T

Check idling

Check battery

 

Intermediate:

Check carburettor/ Wash it

Check 2t pump

Take out spark plug put it against your frame and kick start and see if got spark.... you will shock yourself if done correctly.

 

Expert:

 

Use volt meter check your volage 12-14V check if over or under charge

If it isn't something is wrong with your coil/rectifier/battery.

 

Engine spoil liao... not enough 2T pistom jam.... GASP!!! EEEEEEKS

Too little compression or too much, bike won't start.

If fuel not enough because of carb or fuel line, bike won't start.

If exhaust too much carbon build up, bike won't start.

If wiring is shot, spark plug won't fire, bike won't start.

If ignition timing is off, bike won't start either.

 

When you say you let the bike run for 10-20 secs, were you idling or revving the bike? Dunno about SP, TZM very obvious if your battery gonna die or something, your valve stops working properly.

 

No 2T bike still can start, it won't die off, it will just jam and there goes your engine. If not sure if your 2T pump working or not, suck thumb lor, use premix.

I'm idling during that 10-20secs, My bike is a premix bike

Oh, what 2T? If sparkplug change couldn't be sparkplug foul. Could be carbon build up. Used to have the same prob, kick bike until sian. I decarbed my pipe, washed my carn and the bike starts fine.

 

Pull choke, kick several times without the ignition on, then switch off the choke and kick with ignition on. Play with throttle.

is the battery strong?

can be judged roughly by the neutral light..

my bike similar problem the other day, my mech just clean the carb a bit then change the plug ok aredi..

My bike got alot of smoke last time, Is it a sign that carbon build up? I will try the method that you mention soon, hopefully it works.

 

Thanks

Should be quite strong judging from the brightness..

if thick smoke means start up got problem.most probably is your carb settings and carbon build up.

My SP also got same problem last time. Apparently due to the wiring not connected properly. Uncle cut the socket and manually tie the wire tgt, now ok alr.
