I don't like all the extra plumbing on the carb bowls.
What is a good set worth timebomb? :laugh:

Yes, but the 34CVs are quite a different animal from the 34 flatslides that TerryK is talking about.
Exactly. I tried CVs before and I didn't the "softness" of them. They made good torque though.

The answers i got was they were constant.
I'm talking bracket racers.
I think cost was a consideration here. Roy

The BS34's can be a bit of a PITA to tune. They can have near the throttle response of the 28s', but it generally takes lots of "tinker time" to get there. They will produce more HP. They are a bit touchy at slow speeds when tweaked for better a response. + If your using pods, its highly recommended to use a jetting kit to prevent flat spots, as a these CV carbs require changes to the air jets/passages as well.
The 28s' are a good choice for jetting pods. Fairly easy to work with, and a plethora of info on them here. Despite my love for the 34s', the 28s' are smoother at slow, even when tweaked out. They will have plenty to give thru to about 1/2 throttle pulls, then the 34s' size advantage would take over.
For me, BS34's for sure. For you maybe the 28's for now...
Save the extra cost of a BS34 jetkit, if going with pods.
:laugh: OR DISH OUT THE DOLLARZ! :laugh:

Allright I'm getting tired of hearing this STUFF. I've never had a set of cv's hesitate whatsoever, unless the airbox was off or jetting wrong. WTF are u guys TALKING about? Those carbs are quick! Instant! Right now! Whack or no whack. And if u look at the power increase the z motor had when it ended up with cv's finally, you'll note that it's increase is coming from the fact they took off the vm's and put on cv's. Now. Whats so hard to understand folks? Why hasn't anyone told about this fact? Do you guys even really know how these carbs work, since your so busy playing with other ones? No mystery here. :woohoo:I'm with Steve on this one, 28's over the 34's...
Reasoning, unless mid range to WOT, the 34's won't respond at lower ranges like the 28's will...
Now, if your going to pay for carbs, let's say ~ $500 then save another $200 and go with the Keihin 29 or 31mm CR Specials...
From two different reliable sources, pending your riding style, 1075cc/performance cams/valve P&P or smaller go with the 29mm setup... 31mm maybe in your build but anything larger, why bother.
Low to Mid blows you away.... Pulls like a mo-foe.... Hell, nearly pulls me off the seat... It's crazy I tell ya....
Are they expensive, yes indeed but.... New technology, phenomenal performance, easy to jet... so you get what you pay for....
Just my worthless 2 cents worth....
