Today , I hope to have time with the bike :) All bushings in the engine and gearbox have been replaced ! And bushings looks just like the bushes I replaced with grooves and holes for oil.The exact clearance I do not remember because it's over a year since I did the job , but no shaft or gear was tough to spin. I tested the gears by turning the gearbox by hand.
I have not been driving the motorcycle at all and the engine has been running less than an hour after the renovation . Have not noticed any of these problems before the final minutes .

 It doesn't sound like a problem at this stage, especially if you can hold the wheel by hand or foot (or hook or by crook)from rotating.

 Conversely, if you can turn the wheel by hand in neutral, or in gear with the clutch hand-lever pulled in and without the engine running, I'd say everything is normal. (thus far)
  In the latter case, there will likely be a bit more resistance than in the former case, which I say is still normal.
 Do those checks and then concentrate on something else.

Has tested a bit now. Some problems from the start but I started the engine and drove with the wheel in the air through all the gears , thinking that the gearbox would get some exercise and get oil on all conceivable places.
Now the wheels are still on the neutral gear even when it's in the air. *smiley4*

Thank you all for your interest and help, but maybe I never had any problem :) The future will show

While the clutch is engaged, the clutch drum will be rotating the main shaft.
And this is regardless of weather you are in a gear or not,
The gearbox is full of oil and oil can transmit power which is exactly what is happening inside your box.
The viscoius friction of the oil is causing the sleeve gear to turn which is rotating the back wheel.
When it stops doing this your oil is too thin or the level is way too low.
