HI there hoping for some help here . I bought a 1993 XJ 600s diversion , starts and ticks over fine . but when it warms up while riding it starts getting very temperamental starts running as if its missing, , lack of power between 2 and 4000 revs and vibrates. as soon as it hits 4000 revs and over it seems to smooth out . any help would be appreciated craig
