How many miles do you have up now ?

No direct experience with Z900's, but it is possible for motors to smoke a little after a rebuild.
Smoking badly doesn't sound too good though.
They didn't generally smoke when brand new, did they...

Get a few miles up, and if it continues, then all is not good.
