Easy to jet and tune... Phenominal response...
NOTE: Via SUDCO, they will come pre jetted rich...
So order 1-2 sizes smaller on main and slow jets from SUDCO/other...
For leaner operations here in AZ:
(2) Main size jets down (leaner)...
(3) Slow jets (Pilots) down (leaner)...
Needle jet clip position changed to 4 from 3 (leaner)...
All better now....
May end up with the next size needle (YY9 for leaner mid range) though pending the next couple rides and in performance/operations...

29mm CR Specials for a 1015cc build/stock cams, no doubt in my book... Ok, I'm biased for this is exactly what I have and they are SWEET!

and now a volley from the other side.....i like my 29 vm smoothies.....good idle quality and can be very smooth all through the range if jetted right.....with a 1015 motor, you are probably around a 17.5 pilot and a 115 or 117 main....mine are 17.5/120 for my 1075 and it ran good
and i had other issues (soon fixed) that led to less than optimum performance....that being said, bike hauled butt from 5k to redline......700 for a decent set is market value at this point......in my opinion, you wont be dissapointed.........

Before buying, trying install the carbs and see. I would think they should be real close... 28mm vs. 29mm. BS 34's, yeah I'd believe you'd have to change for ideal and desired air flows.
Same time, how old are the ones you have now?
Hard, cracked, not sealing ideally... Probably best to change anyways. Sure, $30 each but.... This is our beloved KZ's we're speaking of and you do want it dialed in right....
On the other note, 28 vs 29mm CFM air flow into the head will be close. I had my head P&P to the intakes and carbs when sent to Larry so I have an exact match.
Yup, I actually sent him my intake manifolds and carb assembly... The man's work just rocks....!

Side-by-side I would pick the RS34's. I think Mikuni does a nicer job putting the carbs on a rack. The Keihin setup is a little flimsy by comparision.
I would tend to run 29mm carbs on a 1015. I think those carbs give a better throttle response at lower RPM than the 34's - the 34's give awesome performance at the higher RPM...
I love the VM29's - but it's getting harder and harder to find good sets. There are plenty of suspect sets out there now.

Maybe it's non occurring due to my conversion where I relocated the rear sets and my legs truly cover & protect the pods...
Same time, I've opened my legs for some cool air effect on the boys (nads) @ 65mph plus and not had any issues as your mentioning....
Either way, as depicted in the image overlay in green, as can be reviewed the pod are somewhat protected by the plastic side cover and your leg is covering easily 90% of the pod as is so I find this side wind effect to be somewhat hard to believe...
I know, I know.... :S not trying to start a flame war here but I'd start looking elsewhere for your problem in bogging down at 65mph.
With this in mind, ask your self a couple of questions...
If truly side wind was the issue, why only at 65mph does it bog.... This issue would be evident at any speed, legs wide open :blink: , you name it...
In your garage, start & warm up the bike with a cooling fan on the motor... Once warmed at idle or at a steady rpm of lets say 3000rpm... Aim the fans on the pods (side wind effect) does the bike bog down?
When it occurs, if I tuck my legs truly over the pod area, does it pick up speed as expected...
Which pods, cheap or expensive...
No leaks at the intake manifolds...
Ever have the bike Dyno?
Found a place here in Mesa AZ... $20 for a dyno HP & torque measurement... Sweet!
www.ecsdyno.com/home.html
They also will jet & tweak using the Dyno at $100-$200 pending all variables.
In any case.... You save & get the CR specials 29-31mm for your build, get them jets dialed in for IDEAL performance and you'll just plainly love them!
BTW, I got caught out riding a few and between AZ rain storm a couple of weeks ago... Sucked ass big time but had to drive on.... I was soaked and the bike got dirty as hell but I still had no issues with the pods and I'm sure they sucked in some moisture... Now I do coat my pods with K&N filter spray oil and clean them regularly, maybe made the difference.... but the pods DID NOT effect the performance...
This may be a good one for Myth Busters... :S
