Gear shaft slack?

Hey guys. I was hoping that some of you could help me out.

My engine has been totally torn apart, in order to change one of the gears and all of the bearings. I am currently working on putting it together again, but just discovered that there was a bit of slack in the gear shaft ( a few milimeters ) after the assembly. According to the manual, There is not suppose to be anything inbetween the shaft and the bearing. Is it just because the engine is not complete yet?

By the Way, its a Yamaha yz450f 2012

Here is a short video of the problem:


Normal when you put the sprocket on an torque it all up it will be fine.

Great, thanks!
