newbe here
Just baught my first 93 FXSTC. Chromed out with custom paint and many many other options on it. it has some pretty nice upgrades on it. has the hypercharger and Martin Brothers exhaust and a mild cam with the Stock CV carb. my next question is i want to get ride of the CV and go with a mikuni or S&S super. just tired of the Spitting in the carb at part throttle in town. that and more Adjustment is always nice ya know.
Ive been round Harleys, dirt bikes etc all my life and i finnaly got one. im not wanting to break the bank on a carb because im on a budget. would like to find one that eather needs to be rebuilt or what ever. anyone here have any suggestion?
thanks Drayke

Yeah, don't buy a used carb. In my experience and observations, carbs are removed from running vehicles because they have a problem. Then they get sold. If you want a different carb, get a new one. But a lot of people have good results with just properly tuning the stock CV. It sounds like yours needs that, or a rebuild.

the shop i baught it from said he didnt think the guy changed the jets on it. so i called Dallas Chop Shop and they said pull it apart and the low jet needs to be a 32 and the main needs to be a 185 or 190. it does have the plug knocked out so you can adj the air fuel. i tweaked it alittle bit to fatten her up and it helped alot. thanks for the tip.

Stick with the CV , there has to be a reason they still use them even on the shiny Twinkies.
Count how many turns out the air/fuel is set at and turn it out another 1/4 turn and I bet you ll notce big diff.

Yup, the CV is a good carb. Get it tuned by a pro if you cant and you'll save alot of $$$. Alot of old shovelhead riders convert to the CV carb. If you gotta spend the $$ get a Mikuni HSR. It is slightly better than a CV but it will also need to be tuned to your bike. Might as well tune your CV and spend your $$ on beer!!!!!

There's no substitute for skilled input. There is also no certainty that a new carb will work any better, without skilled input. If you can't sort out your CV yourself, don't change it! Go to someone who can sort it for you - you'll probably ride home wondering why you didn't think to do that sooner!

The CV is a good design, there is very little that may wear out that can't be easily and cheaply replaced. Most issues I've seen have been dirt and improper jetting-(basically, someone screwed it up).
