Keyster Mikuni Rebuild kit for Z1

My newly rebuilt Z1B is not running correctly no matter what I do. I used carb rebuild kits from Z1 Enterprises (China) and was told to use real Mikuni parts. I bought “Keyster” rebuild kits from Japan, they are far and away better and they come with a variety of sizes.  www.jp-stores.com/mc/we70630/?act=c2&c=404&icode=5603

Did you ungang the carbs and remove all the parts?  Soak the bodies in carb dip?  Shoot carb spray through all the passages, verifying all the internal passages are open?  I say this because replacing the jets won't clean inside the passages, and there could be gunk inside.

Yes I had the bodies professionally cleaned, we will see if these parts make a difference.

I tried uploading a video of the unboxing but had trouble. Here's a youtube video
