Last couple of rides I've noticed that while down shifting for light or intersection bike will stall. Also it will do it if i get on it hard to accelerate then back off the throttle.. bike is a2012 with almost 80 000kms. I suspect fuel filter is the culprit as it hasn't been changed ever. Also if i burp the throttle while down shifting I can get it to sometime stay running. Never any issues while on the throttle normally.
