Why Engine suddenly die off when riding? Pls Help

[VAN THOR]

My Engine Just died when riding a few distance. When it die off, it need a couple of minutes to start back. What is the cause of it? any help? I tried to change the setting, change engine old, replace my oil filter. But the problem still there. Help me pls. It very dangerous especial when riding under tunnel.

cold start doesn't mean starting up n let it idle for a while. sometimes due to temperature, bubbles form in the carb n tube. that's why u can ride a short distance before it dies off. happens to my bike a lot, that's why i avoid putting my bike under the hot sun or ride in the wee hours when it's cold.

 

if u've ride a few km before it dies off then it's not cold start. it could be ur carburator.

 

filter/tap could be the problem too.

Firstly, don't think there is anything legal or not if your bike stalls...

 

Secondly, there can be a thousand and one reasons why the engine stalls while riding. E.g. clogged carb, clogged fuel vent, loose sparkplug cap, loose electrical connection somewhere, half-dead alternator coil, half-dead CDI, etc etc.

 

Bring the bike to a competent mech to troubleshoot.

 

By the way, changing engine oil and filter will not solve stalling issues.

Please state what bike you riding..

How much is changing 1 carburator cost? less than 100?

I just sent in my bike to Planet Motors on Thursday morning with a similar issue. However I was able to "limp" to the workshop early in the morning because the bike does function correctly at idle and at wide open throttle, cuts out if mid-level throttle is applied above 60kph. (LOL!)

 

The spark plug was fouled and problem solved pretty quick. Why not call Planet Motors tomorrow for a diagnosis? Ah Chong is very good at this type of common problem and he is an ace repairing small Japanese bikes at minimal expense.

Just change my spark plug. but still the same.. change CDI unit.. Better but sometime the problem still come around. Then The mech say to change my ignition coil... But must i? i expensive.. lol

[yinghai]

Ignition coil or magnetic coil?? Ignition coil very hard to spoil.. Have you tried the fuel filter?
