You know the answer... I'm only looking at reviews, before I fitted my restrictor I saw what 1000cc can do. I'm flat out accelerating and GSXR1000 with PC5 and full Yoshi system with a passenger just overtakes me one one wheel. I felt frustrated and at the same time I had a massive wow face and afterwards a massive grin. Can't wait to get full license, so many interesting bikes to ride!
