Mikuni Needle Valve Assembly

This is a complete Mikuni OEM needle/seat valve assembly. 

• Includes brand new seat, o-ring, and viton-tipped needle.
  
• It is important to replace your needle valve assembly during your rebuilds.
• Over time, the rubber tip will become indented and hardened.  This will cause fuel to leak past the valve (flooding) which creates hard starts. 
  

Assuming there aren't any other fuel system issues, a new needle valve will fix your hard starts.
