You would need to describe the noise in more detail for us.
When do you hear the noise, at idle, at a curtain rpm not riding, only when riding, when accelerating, on over run, when does it make the noise? Can the noise be heard when Hot or cold? Where abouts do you hear the noise, from the top of the motor, bottom of the motor, left or right side of the motor?

I went to a trusted mechanic, he heard the engine noise and also confirmed that noise rod knocking.
The noise is from the left side. The bike is only with 23,000 miles and all exchanges were made of oil

Not a bent valve, the motor would not run with a bent valve it's a single cylinder.
Get them to check the decompressioner & pin encase there is a problem there before they pull the motor out. Best get that motor stripped, I would not ride it like that.
