Carburetor choices
I have a 98 FXDWG (45K miles) with a CV carb (45jet & 185 idle jet, jet needle set at middle adjustment notch) that has a stage 1 K&N air filter and thunder header. Over the years it has ran well except for getting noticeably richer. Tore down the carb and discovered that the jet needle is worn, which should account for increase in fuel richness. Harley stopped making the jet needle for the carb. So I'm thinking of replacing carb with a 42 Mikuni. I want a worry-free carb and any advice from you Harley experts that have already made this transition would be appreciated.

If it's just needle jet availability that's the issue, PM me your address and I'll mail you the original needle jet from mine (had 10k on the bike when I rebuilt the carb).
I bought a complete rebuild kit from CV Performance. I don't have a lot of experience swapping carbs on these bikes, so I don't have an opinion on replacing (the S&S does seem highly regarded, though). Mine is running fine with the CVP parts in the original CV.

The CV carb is a pretty worry free carb. I would get the jet needle from Omaha and replace it and be done.
Mikuni, S&S, and CV (OEM) from 1990 on Big Twin on are the three most common carbs for these Evos. All good. Just a personal choice and $$ you want to spend. There are mods to the CV carb that will make it very nice. I've done this on my Evo CV carb. Good luck.

Omaha, Does your stock jet needle have the adjustment notches at the top? I'm wondering if my jet needle may be an aftermarket because it had 4-5 notches for adjustment. I bought one from Harley for a 1200 sportster (Rep said it was same for EVO carbs) that is a solid needle without adjustment notches. I much prefer the inexpensive option of fixing what I got vice a new carb.

FWIW, you can buy the CV Performance needle here.

No notches on mine. Unless things changed year to year (mine is off of a 1990), I don't think the stockers had notches.
