I have the Mikuni's with the BB (and Bub slash cuts). The accelerator pumps are on! I am meaning to get it to a dyno, but life has a funny way of getting in the way. When I do get it there, I will post. (Hell, I don't think I've posted at all in some time - barely have time to even look at this site these days. Then again, if I get some time, I'll probably go ride...that's why we have these things, right??).
