So basically i was just revving the hell of it for about 20 seconds went driving and felt weird. Engine stalled kickstart stuck.
So i opened the engine and there was bearing pieces over piston so rod bearing failure. There was sand in engine via bad air filter from previous owner. Also the piston was ridden about 1500km and the ring cap was 0,7mm on the top one and 0,5mm bottom one. And the needle bearing was shot. So the engine would have failed eventually. I think i know now what the werid side noise was.

Is called seizure by heat or lack of oil. Or screaming from cold start. Or all of the above...
“There was sand in engine via bad air filter from previous owner. “
Bad you never checked as well though bud (the filter) bike stuff 101
The rest is lost in translation, to me.

YouTube & your back tyre says otherwise!
An engine rebuild is always around the corner on a second hand bike, no matter what the previous owner says. If you do as good a job with the engine as you did with the rest of the bike, you’ll end up with a good, tight bike. Just run it in on less than 90% throttle!!
