@Calum im just putting on a new wire i think, do you have any idea where it should go to?

Where is it supposed to go, the other end was ripped off

So i went for a ride, the bike ran as usual, maybe some rattly noises, but i didn't think to much about it. And it ran normal for a while, until i gave it some gas, suddenly i hear a whiny noise from the cylinder, i feel the lack of power, and i barely get myself home. Once i let go of the throttle the bike stops. I took out the cylinder, and i noticed that the crank was filled with coolant, and on the inlet side the piston ring was bent downwards and formed into the piston (probably why it was coolant in the crank). The cylinder has some scratches i think i will get it rebored aswell as a new piston, only thing i worry about is if that some part of the piston or ring has fallen into the crankshaft.

@NINJA could it be blown reeds?

@NINJA it's not like ignition bogging, it feels like a carb or reed problem tbh

@NINJA br9es, never had any problems with it

When the bike is idling and i open the throttle up quickly it bogs, runs on idle but it acts weird. When riding it seems like the powerband comes more suddenly, and not as smooth as before.
I have checked spark plug, which is perfect and brown. I have opened the carb and the main and pilot jets where plugged, i cleaned them and still has the same bog as before. Tried without air filter. When using choke it does not bog when throttle is opened quickly.

I'm grateful for any suggestions.

@declan yeah, it's smoking blue and smells like a two stroke so i guess it's okay

@Calum I drove for a couple of days with premix, and then i switched back to using the oil tank by filling it up, ran premix for a day or so, and after that i have just used the oil tank. Does this mean that my bike has not been getting oil through or does it bleed itself after a while?

@Lorant2 BR8EG and B9es is not the correct spark plug. You should use BR8ES or BR9ES. Could be your issue.
