Works great with your stock YX150/GPX150 head or our new V2 Race Head.Requires no machining to the cases - bolt on and go! Important Note: The intake in the kit is a KLX110 type so the carb will face towards the front fender. Depending on the brand/model of pitbike, this may require relocating the oil cooler or other modifications such as moving shroud brackets.However, the performance gained with this carburetor kit is worth any extra effort it may take to install on your particular model.
