Hi all just joined up.

Hey all! I have just bought a bike after being off 1off one for 17 years lol I kept having them nicked so i lost interest, anyway i have just bought a cbr 125cc just rode it and i found the top end of each gear is a bit flat? Seems like the choke is on but isnt, is this right with it being a small engine? i didnt expect much from it but thought it would be quicker? Thanks in advance,Chris.
