Hi my name is***** need you to see if its loosing spark, so if you can you need to determine if the spark is going away or miss firing, if you have a timing light you can use it as a spark tester, and or get it hot and I it quits, then pull the spark and lay it on the head to see if the spark is there or if you can see some inconsistencies when turning over the engine and observing the spark plug.

Likely that is the issue, then once we determine that then we can move forward, but there are other possibilities, but I would first rule out if its an ignition issue.

Thanks

sorted out my bike,put an inline spark illuminator on the plug lead and confirmed that it still had power to it after bike cut out,that narrowed it down to the carby and i tried another on it and it was fine.
Thanks

Awesome, it really makes it easier when diagnosing, when you can eliminate certain areas !

Thanks for the feedback !
