Hi Guys,

I have a Pulsar 180 UG2. Off late I have noticed a strange gargling( or metal grinding, grrrrr) sound coming from my engine. I dont hear the sound everytime. When I am ripping the bike at 7-8K RPM I dont hear the sound, but when I slowdown by closing the throttle, without braking, I hear the sound clearly. Again, this doesnt happen everytime. When I clutch in it doenst happen.

I have been living with it for the past month or so. It hasn't increased or gone away. I had recently changed my Chain and sprockets and the sound was there before the change and also after the change.

Any idea what could be the reason for this sound?

Thanks in advance.
Cheers!
