not a big four like you guy's..
My little motor don't send as stong an idle/off idle
signal with the big carb's and that's made that part
of tuning them a pita for me.

not even a stock item back then they were special order
ive run em and once theyre set up there great for a streetable track bike better then CRs imho
BE CAREFUL when playing with jet sizes if you over tighten them youll fuck em up lets hope this isnt already the case
the 29s like velocity stacks or pods theyre a aftermarket carb they also like a LOUD scavenging pipe they a great performance carb but as you say the 26s are a great street carb as well so easily tunable and offer good low end torque which is quite fun on the street 29 pumpers where the ultimate back in the day but nowadys i like the rs36 pumpers on my carberated machines

Do these carbs like the pods and header? And O, it never has idled like id like for it to. That's why I was thinking about a set of 26's. Any help ?....
120 main jets and 17.5 pilot jets should be okay (could also experiment with size 20 pilot jets) and according to Z1E, later versions use size 25 pilot jets.
www.z1enterprises.com/Z1CarbGuide.aspx
Scroll down to the 29 smoothbore info and then scroll down further to the chart.
Where adjusting the pilot air screw produces no discernible difference in rpm, it's likely that the pilot circuits are not perfectly clean. It's important that the orifices are clean and clear where the pilot circuits exit into the carb bores.
It's also important that the air jets BS30-97 are clean and clear.
Properly set up, the 29's will produce a strong and steady low rpm idle, and very acceptable everyday street-riding performance, with no extra maintenance requirements, at least with the stock air box and reasonably free-breathing 4>1 exhaust.
However, the stock KZ900 26mm Mikuni carbs are likely the most user-friendly carbs on the planet.
Good Fortune!
