Recently got the bike serviced. Its done 5500 KMS. But soon after the 2nd service , I started experiencing engine hesitation issues , especially around 4 to 6000 rpm , regardless of gear. The engine stutters , almost feels like loss of power OR fuelling issues - The problem is especialy pronounced once the bike is properly HOT O in HOT condition i.e. during day time. I have also noticed , the mileage has come down a bit too. The dealer has cleaned the throttle body etc. checked on BMW diagnostics and they say , the bike is fine. But I know , its NOT fine. Any leads.
