Upgraded Air filter in my RTR 200 BS3 Carburettor 2017 bike. And it gave it new life. there is considerable amount of response time improvement in short accelerations. Although, since it's a carburettor engine, I need to also upsize the Jet, as per some videos , need to upgrade to a rtr 180 jet / 122.5 size one. please consider the same if same bike.
