I bought this kit for a 1915cc engine speedster and sold the speedster! My new engine is a 2110cc and would need 40's, but the new engine has dual webers so I will try them for awhile. My loss is your gain. This kit is from a rebuilding in Hawaii who cleans them and installs new gaskets, o rings, and any other parts needed. He has a video of the carbs being tested which I can provide if you would like. The kit includes: two 36mm D/S carb bodies, 4 velocity stacks, 55 idles, 122 mains, 2 type 1 manifolds, linkage and hardware, gaskets to bolt on , nuts and washers, and hex bar w/ top bases.
I paid $585 for the kit so let me know if you are interested.
