Did you remove the caps over the idle mixture screws and check the passages and o-rings, then set the screws to 2.5 turns out?

"Carb cleaning" is a very general term, and means different things to different people. Complete disassembly and cleaning of all jets and passages can often take more than simple tools and a can of carb cleaner.

Did not mess with idle screws, all seems ok now though.

Yup, most likely fuel flow inside the carbs is problem (clogs or damage). I'll dig up photos of secret passages and disassembly photos when I get to a desktop.

Carbs aren't completely clean. Search here and you'll find that even experienced DIY guys who rebuilds engines on their kitchen tables with both arms tied behind their back, have had to tear their carbs apart 4 times before they got them clean enough.

EDIT: check out this thread for photos of where to clean https://www.ninjette.org/forums/showthread.php?t=317977

Most likely if you didn’t do following, carbs really aren’t as clean as factory new condition:

- soak in heavy-duty industrial chemicals (not spray carb-cleaner)
- hot ultrasonic bath
- flossed all hidden passages with wire/string
- soda blasted all orifices and circuits

Lots of other threads & posts detailing his meticulous work.

Thanks all, it seems the bike is good to go. I pulled the carbs again, cleaned them every port/hole with carb cleaner and compressed air, cleaned jet needles etc.
I also cleaned the fuel filter which had some nasty stuff in it.

I was able to open full throttle and had power , could only do 40 mph in parking lot it was raining will test again tomorrow but I think shes good to go! Thank you guys!!
