Can anyone recommend good quality carb kits. Keystar do a range also Wemento. It's for a Yam DT125 LC. 

Depends if you want original parts or not. You could try NRP or Allens Perfomance

I'd try to find OEM stuff first . 

Sourced a kit from Yambits. Would have preferred Ky Star quality 

A mate bought a Keyster carb needle for his KMX 200 , wouldn't work . Seems you have to use their emulsion tube to match . We didn't try it  as he managed to get an OEM needle . Might be worth bearing in mind . Best of luck .
