Hi Jan.

2 things to check.

1: Throttle position sensor. I’m not familiar with the system for GT650i so you would need to Google it.

2: Throttle body butterflies. To check that both are operating properly you have to remove the tank and airbox and see if the butterfly valves are moving the same amount. This may sound confusing but once you have the airbox off it should become clear. If one is not opening and closing freely then check for damage or carbon build-up.

Afraid I don’t have any other suggestions so I hope this helps.
