Really no need to change carbs on an 80"er with an EV27...the CV is a very good carb and your set up isn't going to outflow what the CV can deliver.
The EV27 likes a bump in compression,but I wouldn't go over 10:1

I'd use the 2-7 and Mikuni too. Very good choices. PM me if you want to sell your CV. Also, Doug has a very good point about lifters. I've seen them go in as little as 32,000 miles, and as much as 49,000 miles. Change the cam bearing while your at it.

If you're going to run the EV-27, I wouldn't worry about bumping the compression. If you're going to purchase a carb, Mikuni, no question or comparison. However, on a mild cam only build your CV should be more than adequate, just get it dialed in, and spend the money you save on an SE ignition module, or an aftermarket ignition like Dyna or Ultima. When you do the cam, do the lifters, everytime.

If you run solo most/all the time the EV46 (or comparable) cam works good in the Softails Running two-up, then I'd go with the EV27 (or comparable) cam. Both are 'bolt in' cams. As mentioned check the lifters and I'd install a set of adjustable pushrods.

Stock CV carb + SE air cleaner kit. Get the bike dyno-tuned by someone that knows how to set up the CV, and you won't be disappointed.

I run the EV27/CV/SE filter/Dyna2000/Supertrapp slipons combo in my 93 FLHS and as other have replied: It runs like it SHOULD HAVE run from The MoCo.

Right now I have the stock cam, T-Header, an S&S carb. If I put the EV27 in, Should I upgrade the clutch? At What point do you do that?
