to answer your first question, the CV does not come in 42mm.  That carb is available in 40mm, 44mm, and 51mm (with variations available through customizers like Woods). 

to answer your second question, your stock coil will be fine for what ever ignition you choose unless you're switching to a single fire ignition- then you have to switch coils. 


I've run both carbs (CV and Mik), although on my twin cams not my sporty.  I currently run a Cv40 on my sporty.  The two carbs act differently although with a stock to mild build sporty they will perform about the same. The Cv40 out flows your stock heads, so changing to a larger carb will not gain you more power.  The Mik will feel like it has more power though.   The Mik has a very fast throttle response since the throttle is mechanically controlled, which gives the illusion of more power.   The Cv has a vacuum slide that controls the throttle which gives some lag.   The Mik is very tuner friendly, although the CV is more friendly to tune for those with less mechanical experience.   I really like the Cv's, but there's plenty of people who like the Mik's too.
