Thanks for all help. Today i removed the pluger and fited a hex key in the hole but nothing happend, i dident hear a click, i only felt resistans so i dident want to push any harder. I havent started the bike yet i will do it later when i change oil and filter. Is there any risk that the spring miss the rod if i put in the rod first ?
So, based on that, the cams were likely not orientated correctly (valve spring force trying to roll the cams back) and there just wasn't enough slack on the back side of the chain to get it too extend. This is part of the problem as to why the spring itself is unable to extend the plunger.
Yes, don't put the rod in first. Put the spring back in and then the rod inside the spring.
You're pretty close to getting this fixed, but here's what I'd suggest at this point. Remove the timing cover off the right side. Remove the bolts and very carefully separate the cover from the motor. If you're careful and don't tear the gasket, it will be easy. The sensor is attached to the cover so just let it hang out of the way. Once removed, you'll be looking at the crank position wheel and the timing chain behind it. The bolt holding the timing wheel is the crank bolt. Put a socket on it and rotate the crankshaft by hand clockwise. While you're doing this rotating, use your other hand to extend out the CCT plunger. You should feel it click a notch or 2. Even if you stop rotating the crank, keep tension on the wrench. This will ensure that the front chain run is always under tension and the backside is left slacked.
Here is a pic of my motor when I had it out of the bike to help you understand what I'm referring to.
In the above pic, the blue arc represents the black plastic cam chain guide that's in the motor. It is only bolted in at the bottom and acts as the pivot point for it. The CCT presses against the back of this chain guide to keep the chain tight. The red represents how to rotate the crank so that the cams will re-orientate. If the cam lobes wind up starting to open the valves, the valve springs are trying to rotate the cams backwards. This causes too much tension on the chain where it shouldn't be and you can't push the CCT plunger out against this force. By rotating the crank with your right hand and taking the tension off the backside of the chain, your left hand is free to push the plunger out a notch or 2.
Also, with the bike on the sidestand, removing the timing cover won't cause you to lose any oil. There's no need to do anything other than removing the 6 bolts for the cover and carefully removing it.
