Which carb?

I'm planning on changing out my stock Carb to a Mikuni Carb. My bike is a 95 with SE heads, S&S 37g cams and thunder header exhaust.
I see they offer 3 different bore sizes, 42,44, and 48. I'm looking for some better performance, but just not sure which one will fit the bill.
Hope this is in the right forum. Thanx in advance.

Isn't a stock CV 42 mm? If I go smaller will I get enough out of it? Just want to be sure I get the right one. Don't want to go too big and over do it.

The stock CV's go out at 40mm - the Mik 42 is what runs good on the 95 with the Andys 37's .. the deal of the day is being offered by Dew for 2

Missed out on the Mikuni from Dew. So am I looking at the easy Carb kit from Mikuni? Want to use my throttle cables, AC cover etc.

A stock CV40 will make more torque than the Mik42 and quite adequate for your motor. You can also have the CV40 bored to 44 but really not necessary. Consider a Yost kit for your CV40. The Mik42 will make a bit more HP on top but not enough to register on the butt dyno.

I would stick with the CV. I run a CV44 with a Yost kit on my 107 '02 FLHT; 10.5 CR, Dorfman's Pro Street ported heads, TM600SM cams and the much maligned CV works just fine. I could probably get a couple of additional HP with Mik48 but can't see spending the money and the get to listen to the slide rattle.

The Mik 45 is a bit on the large side for the 95/37g. The Cv is a good carb but I found the Mik 42 on the 95'' alot more responsive with the 37gs.

One way to find out what ya prefer ... try one, if ya dont like how it pulls you can always get your money out of it. Too bad ya missed out on the Dew Deal.

Be patient one will surface

Which carb?

I ran the mikuni 42hsr on my 95" with tw50 and it was great. Now going to run the 42 on my 107 cause its a easy to use and works well.

Another thing to think about is the manifold. 45mm needs a big bore manifold, 42mm can use the stocker.

I don't know what the SE heads prefer, I went up in size mostly because of the big ports/valves on the Zippers heads on mine. But I also went from flat top pistons to pop ups, and swapped the 37Gs for 585Gs. All those changes together were worth about 17HP and 9TQ, but it definitely moved the power to the right. If you plan to stay with that cam, 42mm is probably better.

I don't know if it was because the first carb was old and worn, but when I put on the 45mm, I got about 5 more mpg, from 38 to 43. The 42 had been on there since the PO made his initial set of mods right after buying the bike new. I tried fiddling with jets and stuff and even put a rebuild kit in the 42 with no improvement in mileage. Since both carbs cost the same, I went 45 with the SE big bore manifold.

If you're bothered by noises, you probably wouldn't like the noise the slide carb makes. You can hear it working. Sometimes I don't like it, mostly when I get another new sound and the carb kinda masks it when I'm trying to ID where its coming from.
