which carb do you recommend?

[gsxrboy96]

98 inch , 10.65 to 1, tman 590 Cams,fat cat ,  this is in a bagger, hsr42 or 45 ..... Or maybe a cv44, I've jetted and used the 42 and 44, no experience wirh the 45, ready set ....go ! 

[turboprop]

CV44 would be pretty stealthy.

[Merc63]

Mik 42mm

[rigidthumper]

i like the CV44 for milage and performance. The Mik has a better perceived feel, and a lot of folks like the better feel.  I've never seen a difference on the dyno, tho.

[saddle tramp]

CV's will get you good mph, Mik's will to but you need to know the carb and jet it accordingly.

[speedzter]

The answer is they will all work well when correctly jetted.
I would choose the 45 Mik', otherwise whatever you may have on hand.

[Nowhereman]

Mik 45 and you will be set for any engine upgrade later on.
Slight jetting is all you'll need for the idle circuit and main.

[Hillside Motorcycle]

45 won't be too much, nor would an S&S G with a T/jet.

I was told a 42 Mikuni would support 120 HP and give great low end torque due to the velocity whereas the 45 would do better on HP but you might lose some low end torque depending on the heads?

[Hillside Motorcycle]

120 hp with a 42, would be like asking for a deal that God gave Noah.

Who told you that?

[05FLHTC]

X2 IME & IMO I suggest the Mik 45

Ditto, Don't listen to that "knowledgeable" person anymore...lol

[twincam8888]

I'm a big fan of the 44mm CV carb. Easy to jet, good mileage, large enough for a 98".

[Rugby_fxdwg]

I have a similar build and went with the SE CV44 because I didn't want to hear the MiK chatter. Its an Ultra with lowers and didn't want to hear it reverberate off the fairing and lowers. Performance wise, I would think it would be a wash. I think Max did a comparison of the three main carbs on the market, he would have some great insight...so would many of the gentleman who offer their expertise on here like Larry, Scott, Bob, Don, prodrag....too many to mention.

[Carl 1969]

What's the consensus on Woods-modded CVs?

[TorQuePimp]

44 CV

Mr Woods seems to know a few tricks with the carbs....ive had two liked them both

[Nowhereman]

That"s precisely the point.
If you have to go to someone to get a carb modified, you have lost.
Note: no one I know runs a CV for performance.
If they are they are trying to make a point that can't be won.
Take that CV up into the mountains and back down then lets see how you like it.
Miks don't need to go to someone to get modified.
Literally out of the box they run good.
Once you read and understand how they work, you can adjust them to suit your motor needs in less than 30 minutes.
Get a Mik and you will be happy and have room to modify jetting for almost any motor useage.

It weird how people think.
The club here likes the chatter.
We call it character.
It means get ready for some serious loss of rounds of beer.

[MikeL]

98, S&S 625G, Kirby Heads, 11:1, Heavy Breather, Freedom pipe. I have a CV44 no complaints here. No modifications other than jetting. I last checked mileage 39.9 mpg pulls like a bitch great drive-ability, trouble free.

If you take a CV up in the mountains, because of the vacuum operated slide it will run much better than your mik. The slide helps compensate for the altitude where the mik is jetted for where you live sea level or where ever. I've had both and ride as high as 8,200 feet and live at 3,500 and have ridden to the coast many times. The mik is a good performance carb but the CV is a good all around street carb.

[jrgreene1968]

If a cv is enough for a 98" and a mik 42 is supposed to flow more than a cv44, why wouldn't a mik 42 be enough

[NHBagger]

A 42 Mikuni would be enough with your present setup.  I run a 42 on my 106 and the AFR numbers are fine.

On this comment, I would disagree.  I've had my Mikuni HSR42 from -200 ft (Death Valley) to 14,110 ft (Pikes Peak) and have never had to adjust the carburetor, it runs flawlessly.  It was perfectly tuned at 1000 ft with a a/f meter.  And!!, I get 44-50+ MPG.  I would put the Mikuni against any other carb, any day.  The Mikuni is the best steet carb, it doesn't feel like a mush bucket when you twist the throttle.

[05fatboy95]

I ran a mikuni 42 on my 107" and it was flawless. I did switch to a 45mm trying to chase a few extra ponies. Set of the pants no difference but the dyno showed 6hp increase. Same dyno.
