Harley Carburetor

Harley CV carburetors are the finest carbs ever used by the factory, however due to government regulations these carburetors are greatly restricted in their output. Your Harley's full potential can be released by installing this simple to use kit on your stock carburetor. The Harley-Performance Stage 1 Kit was developed based on 20+ years of tuning experience to meet the needs of real world riders.

Stage 1 Carb Kits are available for all Harley models from 1990 to present that use a CV style carburetor. Kit includes complete installation and tuning instructions.

Complete Stage 1 Modification Kits include:

  • Performance Slide Needle for Improved Midrange
  • Light Weight Screamin' Eagle Slide Spring
  • Assortment of Two New Main Jets
  • Assortment of Two New Idle Jets
  • New Emulsion Tube
  • 2 Replacement Fuel Line Clamps
  • Drill Bit to Modify the Slide Port and mixture plug
  • New front gasket
  • Easy to follow installation and tuning instructions
  • Special - receive a free Stainless Steel Screw Kit!

Your carburetor will perform at at it's peak without compromising drivability. Faster warm ups, smoother response, steady idle characteristics, and reduced "coughs" or hesitation compared to any stock set up. Wake up your engine's potential and feel the hidden performance within your Harley. Also a great way to renew any Harley carburetor that has been neglected or incorrectly jetted.

Combined with any exhaust and air cleaner upgrade, modification of your Harley's carburetor is a must to achieving a true Stage 1 upgrade. Unlike race kits which require dyno tuning or installation of odd hybrid parts, Stage 1 Carb Kits from Harley-Performance utilize your carburetor's built-in tuning capabilities. By following the included installation and tuning instructions you will be ready to ride, for far less than the cost of a visit to your local dealer to calibrate your carburetor.

My stock Harley was so lean that it coughed and stalled from the day it was new. I was prepared to sell my motorcycle before installing your kit. Now my ride is perfect.
Thank you for a great solution.   Glisur - Oslo Norway
