Hi, my Duke 250 stalls a lot. It runs completely fine if I keep revving. But stalls 70% of the time when I press the clutch and release the rev to come to a stop. Even when I get lucky and the bike didn't stall, the RPM would drop to around 1000RPM and would go up again to normal values. The idle RPM also is unstable, its starts at around 2k RPM and would drop to around 1K sometimes and then come up again.


I have changed the spark plug, changed the air filter and cleaned the throttle body but still doesn't fix the issue.

Any answer is very much appreciated. Thank you.
