This is the only 1.125” (28.575mm) Carburetor built for Open Yamaha KT100 Racing Carburetor runnning methanol.
Where the others fall short are in their initial design and intent for other engine applications. While all things are possible, the X380 is a far superior carburetor from start to finish. Our Intimidator Carburetors replace our 3+3 Twlight Zone Custom built Tillotson carburetor($600-1000+) with a blank body ready for any fuel circuit and modifications to fit any type engine. These carburetors are built with custom plate stacks, billet needles, and our EC signature 3 piece throttle shaft.
The X380-8 is designed for the Open Yamaha KT100 2-cycle
