I need some clarification on the problem. When you pull in the clutch and put the bike in gear with engine running, what happens? If you let out the clutch lever, then what happens?
On Kawasaki road bikes, they will not free wheel with the motor off and the bike in gear and clutch pulled in. Their clutch plates have far too much friction. You can push them with some effort, but they don't roll very well when the motor is off.
So the question is does the clutch work properly with the engine running?
Was there a problem with the cable?
Usually you can move them but they don't roll easily because Kawasaki clutches have a good deal of drag to them. As long as it's all working correctly then you are good to go. Happy riding!
Happy to help.
