today I visited the mechanic for checking noise he said this is not gear noise while shifting the gear to neutral position and then press the race pedal the noise is still coming in ideal position while the gear is in neutral state.
The other thing is the noise sometime comes and sometime not. Its very CHoor fault i should say. If its a gear problem then why the sound is coming while in neutral state?
The mechanic mentioned there must be some bearing issue or belt issue I also noticed that my right portion belt is tearing down and one is very hard.
