Excuse my english (I´m from Barcelona - Spain). My CBF 1000 between 1500 and 2000 r.p.m. doesn´t function very well. When I come to a semaphore I have to press the clutch if I do not want that the engine of blows (this has never happened to me with other motorcycles that I have had of 550, 650, 750 and 1200 cc.) The motorcycle only has 10000 kms. I took her to the shop and they said to me that this is normal. Someone can say to me if it is true.
