They are somewhat unique and would be a worthy addition if you were building a hardtail, or something along those lines.  In terms of more mainstream usage, they seem spendy compared to rebuilding a set of stock carbs.  And one nice thing about stock, you don't need to fart around with jetting.

This topic has come up many times and my view remains the same (it is only my opinion) auto manufacturers siamees carbs for reduced maintenance and better gas mileage (a compromise) but every engine tuner since the 50's has, where the rules allow favoured one venturi per cylinder (carb or throttle body) this allows for a shorter intake runner and a straighter path into head for the intake charge.
With regards to "their claims" - according to advertised claims, an exhaust, jet kit and K&N filter will make my "K" faster than an injected GPZ1100 (they all claim 10 - 15 percent power increase for their products) so I don't know why the factory bothered designing a new head & cams etc. Take Nessism's advice, save money and go faster :)

As said, its come up numerous times. Any engine tuner will tell you their claims are utter rubbish. 
if they worked as they say they do i would think the big four jap bike manufacturers would have saved shed loads of money by only fitting 2 carbs instead of four.
to get the best performance from any engine the air fuel mixture needs to be specific to each cylinder. You cant do that with one carb supplying more than one cylinder and expect best performance.

I don't know why anybody would think that anything other than 1 carb per cylinder would be better or faster.

The factory thought it was necessary to engineer the engines to have multiple carbs even on twin cylinder models. There is more HP potential when using one carb per cylinder, and I have never met anybody who wants to make less HP.

Less carbs are only good for people who can't tune carbs.

I think the main allure of these carbs is that they are new.  Many people are fearful of carbs, and they think that buying these are a shortcut to getting their bike running well.  The twin crowd seem to be the most likely to adopt.

My 79 400 came with one installed. After a lot of messing around, changing pilot jet and jet needle I had it running great. I was hoping for better support when I emailed Murrays but all they told me was "don't degrade it". That was no help at all. So don't expect a bolt on perfectly tuned carb out of the box.
After getting it dialed in I took a lot of trips in a lot of different conditions and it performed well. But I have to agree with what was already said, individual carbs are better. Cheaper too depending on what you have and what you want.

Hi, I have a pair of Murrays installed on my KZ1000 and I'm not complaining, low maintenance and fewer headaches, but if one thing needs to be made clear, nothing beats 4 carburetors properly tuned.
