They're not terrible carbs but they are limited in tuning parts. It's hard to get the off idle transition right. Most just hide it by adjusting the idle overly rich.

Despite your experience you seem to be missing a key part of the equation. Specifically how the fuel is metered by the main jet and needle.

Yes, if a CV carb is to be exclusively used at altitude you would make a change, most likely to the pilot jet and screw as the idle circuit is not effected by the main needle and vacuum diaphragm.

But the main jet and needle will meter less fuel to better match the reduced air mass/oxygen.

Again the Mikuni does not, it will deliver the same amount of fuel resulting in a much richer mixture at altitude since the needle will pull further out of the main jet than the CV in the same circumstances.

I haven't tried to keep track of who's in which pissing match, and I kinda wish that a few posts in this thread could be deleted that aren't related to carbs or EFI at all.

We're really splitting hairs here. You can look at NRHS or Hammer and see the dyno tests proving the Mikuni can make more HP, but without a doubt for cross-country riding from sea level to milehigh+ altitude and temperatures ranging 40 to 100 degrees and rain then desert, the CV carb will get you there faster (because you don't have to stop for adjustments) on less gas.

No matter what carb, if you want perfect A/F ratio 100% of the time you would have to adjust for conditions but with the CV you will do it less. So is it fair to say the HSR is better for performance, but the CV is preferred for normal every day riding?

I've run both and I'd rather have the HSR for normal everyday riding. But I like my bikes to run well and don't do my jetting (or mapping) by internet polling...
Have fun. I'm done as this is clearly pointless.

yep I preferred the carbs I got one of the last carbed 1200C in black too
no wobbles i had it for 8years it was a 2006 and had just 10 thousand was just starting to smooth out when i got it

I got a great deal on it as the previous owner hardly rode it and had fallen off it at the lights at a standstill
on it when I got it its never been any trouble except for it spitting the clutch spacer rivets a couple of years back and then the throw out bearing last week i have done over 20 thousand miles on it since I had it
