2010 R1 Cold Start issue?

11k km on it, the bike was starting and running good on a cold start (Not cold weather only, when its idle for few days). But since some time I'm noticing on a cold start its starts fine and remains in idle no issues, just the idle is lower than normal (800-900) But if I accelerate and release the throttle, when the RPM falling down its tends to drop power and engine stalls. Its like its losing power when the RPM is falling. Its even happening at very slight acceleration. No issues if I accelerate and keep steady in any RPM.

But after just 100miter run no problem at all. I even keep it start idle for two minutes after a cold start before the run, but still this happens just at the beginning run.

Exception is I used Abro Fuel Injector cleaner since some time and using it for last two full tank. Could this due to the foul spark plug? Few time back cleaned the air filter and all cleaned inside.
