After buying some jets they would not fit my carburetor. Turns out I had the dynojet tube who uses their own crazy thread sizing different from that of Harley. Bought this emulsion tube and it takes both Harley and the CVP jets I have. Problem solved and bike runs great now.

<p>Fitted this, needle jet and CVP needle to my high mileage sportster CV. Wow what a difference. Didn’t change or adjust anything else, throttle is crisper and starting better. Awesome</p>

<p>Easier to buy the parts seperate to get past long waits for carb complete kits</p>
