To find the carb size, you have to measure the inside diameter on the engine side of the carburetor. You may already know this but, once you determine what your carb is, call the pipe manufacturer to get the jetting specs. If you bought the pipe from a performance shop, they can also provide this information (often better). They will need to know all the mods. These will be starting points for jetting that should be pretty close.
