Review on 🚗 Carburetor Compatible with HONDA XR100 (1981-1984), XR100R (1985-2003), CRF100F (2004-2007) (Fits XR100 XR100R CRF100F) - Carburetor for Honda XR100, XR100R, and CRF100F models (1981-2007) by Josh Hamler

As well as some others mentioned: Unbolt the old carburetor. Remove the cable and needle guide from the old carburetor. Clean the needle and set it aside. Refitting to a 2003 Honda xr100r.turn on the gas again. Launched on second hit. Lower the idle a little. Like Jason said. Since 2018. The only hiccup was when my fat fingers dropped the carburetor nut into the engine. Lay down a rag and prepare a magnet to remove the fallen nut.
