Motorcycle wont start ?
The motorcycle was idling like normal I went inside to pick up my helmet, then when I got back it just turned off, I Cranked it but no success , I checked spark , it is OK, It just turns on for like just 1-2 cranks and stops again over and over...
I had the carburator at a mechanic he Cleaned it , now when we push start it , it starts and bogs...

Sounds like 2 problems:
One: check battery. Bench charge it. Check/tighten connections to it and starter/solenoid. Bypass solenoid with big insulated screwdriver. Still no good? Tear down starter, probably brushes. Can turn commutator in a drill with sand paper.
Two: make Sure of spark --hold plug(s) (All of Them) to head while cranking. See hot sparks?
Ok, then, put them back in, try starting fluid. If it starts, you still have a fuel flow problem., If it doesn't; well, spray starting fluid around carb/manifold boots. Still nothing? You may have jumped timing or lifter(s) broken, etc, stuck valve(s).
If carby problem, make sure a good flow when tap On. If a vac actuated, sucked on the vac line and see. Must Flow, not a dribble--this means bad valve/clogged. Clogged once can be Clogged Again, Nothing is absolute . Remove gas cap--may not be venting.
Check carb bowl(s) Any gas? If not, tap on needle seats. If gas, you still could have clogged idle/slow jests. Any mech that "rebuilt them" would add a $3 inline filter..

Check the battery. Calcium batteries have a habit of instant failure and what you discribe happened to me on my FZ1. I replaced it with a lead-acid battery which I much prefer and that solved the problem.

Is there gasoline in the tank?

I'm did you turn off the gas at the gas tank valve and forget to turn it back on

" ... just turns on for like just 1-2 cranks and stops again.... "
Does compression goes good and bad? no.
Does spark goes good and bad? no.
Which leaves gas. You are getting a dribble of gas into the carb, runs until the float is empty.
You are not getting enough gas, clogged gas filter, leaky gas switch thingy.

Is it getting any Fuel? Check the petcock and look in the tank.

I can tell from your detailed description that "the motorcycle" is a 1963 BMW R60. It's got worn brushes and a slightly flat spot on the starter motor armature which is why it won't really crank, and it died and won't run because the carbs need a rebuild. Specifically, the carb vents are clogged, and the floats ain't a-floatin'.

You have spark. Next check fuel and compression. If no success go see your mechanic.
