I don't know this problem has been discussed here before, I did some search before posting but couldn't find anything relevant so posting one.
My Honda CB Unicorn 150(2009 Model) gives a whining sound while riding, but never gives the same sound when bike is in neutral. When the bike is in neutral, how much hard I rev the engine, I can't here the noise. But while riding after crossing 3000 rpm in any gear it gives a whining sound. I can here the same noise in other old unicorns as well(new unicorn never gives that sound).
When I checked with local mechanics, one guy said that sound is coming from clutch plate, it needs to be replaced. Another guy said, it coming from the meter, if we service the meter whining sound will be gone.
Any thought on this guys. Thanks in advance
