I have just bought my bike yesterday for £350 with long T&T. Seems to ride ok until i am in the 40mph bracket and it seems to not be firing correctly or has flat spots and won't pick up. If i turn the throttle after a couple of seconds it starts to pickup, but not immediately. Now i know it is an old 250 and i have not rode a bike for over 10 years, but i am certain it should be more responsive than it is. Any help or advice would be great.
P.S. Just joined the site, looks great. By the way i live in Manchester, England. Not quite as glamorous as some places on here.
