Product info for this Genuine Keihin OEM Carburetor

  • This is NOT an aftermarket Carburetor; these original carbs can cost upwards of $800 U.S.D. from the Dealer
  • This dirt bike carburetor kit is ready to use on any two-stroke dirt bike and eliminates any wiring issues with a more simplistic bolt-up and ready-to-use carburetor
  • We recommend the new throttle assembly option for older dirt bike models
  • Carburetor intake side boot sizes may vary, and some intakes can get stiff over time, so it is best to heat or replace the rubber mounting for easier installation.
  • The video below shows our Keihin 39mm Replacing a Mikuni TMX.
