Are you sick and tired of jetting your bike for elevation, every time you ride somewhere new? Are you sick of tweaking your air screw every hour as the temperature rises on your ride day? Are you tired of inconsistent power delivery and surging from your OEM carb, or just can't seem to get it dialed in?  
 
MXR has the solution
 
Lectron Carburetors are 100% JET FREE! That's right, no jets. Fully compensates for changes in elevation and temperature. Pre-tuned from the factory for your specific make & model machine. 
 
With a Lectron Gen II Carb you can expect:
 
-Incresed power
-Smoother power due to more even fuel metering
-A more unified & usable powerband
-Increased fuel economy (skip the big tank or pair for the ultimate range!)
-No jetting, ever.
 
**Add a metering rod tool, to ensure damage-free Lectron tuning, should you add a mod to your bike requiring a fuel delivery alteration. (Compression alteration, porting, etc)
