As you guys know I have been working with a guy who claimed he could make an S&S better than a Mikuni. He was wrong, he can't even make it as good. I changed to Mikuni after finding that the S&S can not be tuned for a full throttle range there is nothing you can do to not have a dead spot. You can move the dead spot to anywhere in the throttle range you want it at, if you want a dead spot some where, I however do not. I want full throttle response through out the throttle range. Even with all the modifications he made to the carb it still never measured up to a Mikuni. Now on my single carb manifold I have a 42mm flatslide Mikuni and it runs better than ever, and looks very cool as well.
