The Lectron carb absolutley EQUALS performance. More people trust it for performance than any other carb.  You can adjust it to fit your riding needs, basically out on the trail.  Here are it's known benefits:

This listing is for the all new Billetron 38 carburetors by Lectron. This is the short body product with a 78mm overall length. 

Performance Improvements:

How? Through These Design Changes:

  • Significant bottom end hit - Torque and HP increases of 10% over competitors
  • Increased throttle response - Peak torque availability at lower RPM ranges for unmatched power availability
  • Faster power jet activation - Meaningful increase in CFM, signals activation earlier increasing top end performance and fine tunability
  • Improved Idle - Centralized and focused air flow to the fuel signal creating improved idle consistency
  • Increased Tunability - Finer adjustments and ease of access allows for easy on the track fine tuning
  • ISO Certified precision machining paired with billet aluminum construction for unbeatable product consistency and performance
    • New bore, bell, and slide design that maximizes airflow and throttle response across all throttle positions
    • H-Style slide (aluminum with newly designed hard anodize coating) reduces friction throughput throttle positions allowing for very controlled throttle
    • New metering rod adjustment mechanisim (1/8th turn increments) for fine tuning
    • Horizontal power jet screw that is adjustable by hand for quick and easy on the track tuning
    • Finer threading for idle adjustment allowing micro changes for tuning 
    • New top cover design with two screws and locating dowels for ease of installation and adjustment
    • Gasketed body halves with dowel pins for consistency of performance and easy cleaning and rebuild ability 
    • Industry standard Metric hardware
    • OEM throttle cable compatibility for most two stroke applications for user friendly installation
    • Shorter overall length and height for easy bolt on installation
