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.

The Short body on my ktm 150 was a game changer and more adaptable to 1-4k elevation changes with no adjustment needed!

Over expensive.. no definite explanation of what you are getting for the massive amount of money, also you can get similar carb and full assembly to go with it for 26 bucks on ebay
