<![CDATA[1998 TDR 125 4FU Engine Cutting Out When Warm]]>Hi,

Hope you are all well.

I have been having some issues with my TDR. The engine keep cutting out when it warms up.
This problem originally only happened in 6th gear on the power-band.
However its since got worse. I wondered if anyone has any advice, I'm hoping its not the stator.

What I have done so far.

Cleaned Carb & Both Jets
New Spark Plug
New NGK Cap
New HT Lead
New Coil
New Voltage Regulator
Checked Fuel Flow
Checked Air Flow
No overflow Pipes are Blocked

Swapped out the voltage regulator got it up to temps and it ran fine.

Does it happen at any rev in particular? Throttle full open might be power jet? Does it start up straight again?
If it doesn’t have you checked the spark at the time?…

Sorry, more info is King! 🙂 …
