I removed the EFI from my 96 and put a bone stock CV on. A jetting to match the air cleaner and exhaust and it is hokden. Mileage went from 32-38 eith the MMEFI to 43-49 with the carb. And better actual performance. Will probably need to rejet again when I finish the cam swap. Easy-peasy.

The CV carb on your bike is just as good if not better then others and is pretty easy to use n o reason to look for anything else unless you are having problems with the weight of your wallet and your peace of mind.
As far as better well here is another point of view for you. If it aint broke don't fix it.

I call bullshit on your last claim. I've run them both on the same bike, and I'll give you throttle response and maybe power (haven't dynoed either setup), but no way in hell can the Mikuni match the fuel economy of the CV carb. When I had the CV carb I AVERAGED 50 MPG under nearly any conditions. The only way the Mikuni will see 50 MPG is downhill, with a tailwind. When I put the Mikuni on my fuel economy dropped from 50 down to 40-42 MPG. Even putting the "mileage kit" in the HSR42 only improved it to 45 MPG under ideal conditions.

Well odd that this should come up as I was about to post about something I discovered today.
My 1999 TC is being a dog to set up, the carby just doesn't wanna give me the low down grunt I think it should...so I stuck on a CV from a 1987 FXR that I had lying around and its way better!!!!
So, maybe the OP has been told something about late-model (1999) CV's as compared to earlier ones....any carby geeks know if the specs changed along with EPA demands?

The CV came off a 87 FXR but no idea what year the carby is except that its old as it has the round floats.

Maybe off-topic, but I Dynojeted the carb on my '98 FLSTS (EVO) back when it was new.
I installed a set of Samson (straight) Slip-ons w/S&E AC and I wanted to be be sure that the bike was running rich enough to keep it cool.
The bike get about 40MPG (not great) but it's ridden very little and the pipes are dark gray and it really sounds great and idles almost as good as a Shovelhead.
Last spring when I started the bikes up it ran like crap.
I tried everything from plugs, cleaning the A/C, fresh fuel, new petcock and filter.
I took the carb off and disassembled it and used compressed air to clean out all of the passages....NO change.!
I removed it again and replaced the accelerator, high speed jet, rubber diaphram spring, replaced the intake seals and again compressed air.....NO change!
For the THIRD time, I removed and disassembled and again used compressed air......Eureka!!!
All I can think is that there had to be something trapped somewhere inside the carb but darned if I could see it.
I'll have this bike forever, but I prefer EFI even though it's expensive to repair when it has problems.

the only reason i say that i thought my carb wasnt any good is because i just installed a ev-27 cam and i felt like it wasnt performing up to my liking, so i started reading and researching and many people say that the hsr-42 was the best. i later found out that my bike is a california model and is choked down to meet emissions. so now i am just goin to change out the idle and main jet. 180 and a 45 ? any thoughts.
