I have bought new YBR 125-G two weeks ago. It has only been driven 300kms. I took into consideration the manual and have not rev it more than 6000 rpm (except for two times). The weird noise is noticeable from the left side of the engine and it seems like the noise is like something grinding inside, and sound of friction.
I am worried that how come a new bike produce sounds like this, that too in its initial 300kms. Please let me know and if any other YBR user have experienced this issue. I don't want my engine to be opened in its initial phases.
Explaining the sound even more it comes from cold engine but is more noticeable when the engine is hot. Should I visit the dealership or wait for initial 1000kms for a proper tuning?
