next up grade for my 02 fxdx will be a new carb and air cleaner....most suggest mikuni ,others say s&s, what about the edelbrock 2 bbl..note new h.p. manifold will be used also

 

i like S&S carbs and for inline set ups (not harleys Mikuni) but both are great carbs... why are you changing out the carb bud? what type of motor work do you have done?

 

never liked the cv ....had s&s on my 96ci ground pounder ...due to $ up grades are 1 at a time ...carb now ...gear drive cams later...only want bout 85-90 hp for now

 

I like S&S. They are good simple carbs. A Super E would work great, but how much better that a CV, probablly not all that much better. I myself wouldn't swap out a CV for any aftermarket carb unless the CV was worn out and needed work. But if your hearts set on a swap, I like S&S.

 

The only advantage over your CV with an S&S is the simplicty. You will gain nothing in performance and lose out on self-regulation for altitude and temperature i.e. IMHO its a waste of money.

The only carb that you will feel a difference with is a Mikuni. Even then it won't be top end, it will be throttle response; the power will come on quicker because you lose the vacuum slide lag of the CV.

There are downsides to a Mikuni though. Like the S&S, the AFR will change significantly from mountain to coast and from summer to winter. Its also more fussy about tuning; with the CV there's a small range of jets that work OK for the common range of A/C & pipes but the Mikuni can have a big change in jetting just for a pipe swap. For that reason I think its best to dyno tune a Mikuni.

 

agreed with out the motor to back it the carb will do nothing bud

 

I've always been a big fan of the stock CV..... with a little work they perform great and are uber reliable.......

 

These guys are nailing it.....nothing will out perform the stock CV carb with a tuner kit when needed. Having worked on all three though, I would opt for the S&S if a change had to come.

 

I agree, stock CV 40 tuned properly is an awesome carb.
If you're going to upgrade Mikuni is the way to to. I have an 88 inch stroker
in my 95 fat boy and I'm running the stock carb.

I don't know what the other guy is talking about, Mikunis are easy to tune.
Maybe it's just me from all the MX bikes I've done, but they're a snap.

S&S is good for ***** out WFO drag racing and you're also stuck to using
their A/c set up.

 

I used a 40CV on my 88hp Sporty, a 44CV on my 100hp Sporty and currently a 51CV on my 111hp 103 FXDXT. I think the main reason most slam the CV is simply because they can't sell 'em; only HD has them off the shelf (other than the re-worked Woods units, but what does Bobby know about carbs.....)

I heard one grey beard refer to the S&S as one step up from a gas soaked rag.....they have there place, but not on my bike for all 'round driving. My theory is you can over carburate with a CV and get away with it because it's a CV...mine have all worked well with nothing other than factory jets to suit the build.
