Finally spent some time and got a Mikuni 45 dialed in with the digital AFR reader and have to say the Mikuni will hands down out perform a prepped CV, the CV is still a rock solid carb probaly the most versitile carb out there but the Mikuni has some more giddy up and smooth as sillk with quicker response. Had a few growing pains tuning the Mikuni and started thinking I made a mistake but once understanding that one change affects more than one area, was able to fine tune it with good results.
