2021 Keeway K Light 125

[Jim M]

Hi guys, looking for some guidance. Just bought a 2021 keeway k light 125 with 2k miles with a issue.

Issue starting, plenty of spark. If it does start idles fine for 5min or so then it will stutter. Will do this a few times then die. If I run it you can feel the stutter and will cut out when you stop If you don't keep the revs up.

Injector has been renewed, values check all fine, all connections checked and cleaned, stand switch, clutch and neutral  renewed. Charging system replaced.

 

No codes on the computer, all fully serviced. Banging my head off the wall with this one.

 

Any advise welcome.

 

Carry on living your best lives.

Sounds like the fuel mix is too rich. Check the colour of the spark plug, see if it's black or sooty. 

 

Could be a dirty air filter ( just because it's been serviced doesn't mean it's been checked). Or a bad temperature sensor which would mean the ecu sees the engine is always cold.
