Is it possible for you to post a youtube of your no-start cranking, and the loping idle that spins the rear tire?
The EFI system used in the LIKE200i needs a healthy battery - after which it is famous for its near instant starting, in all weather and temperatures.....if the throttle is not touched! Just 'key on, pull brake lever, push start button'!
Any hard start with a LIKE200i which occurs after you've added the correct amount of oil following an oil change is coincidental. One has nothing to do with the other.
The LIKE may require a touch of throttle when starting after a lengthy very high speed ride - otherwise the throttle is never used during the start procedure.
