quickshifter or gear

Hello, I´ve recently changed the whole sprocket kit in my SFV2 -22 (I asked a workshop to do the job). The main differense now is that the front sprocket is a size smaller (one notch less). Otherwise the back and the chain is the same. Yesterday i took the first longer ride after the change...

Im about to totally go insane here, have the two bolts holding the rearset to the frame off but cant for the life of me figure out how to get the gear lever off of the rearset/bike any help very appreciated
