I have a TZR 250 the since I have changed the needle valves in the carbs it
does not run as it did. It is not so easy to start and like a lot of choke
when it used to start with little or no choke. When I rev it, it revs up
fine and when riding in the powerband seems to run fine, but coming off the
throttle it seems to take ages to rev down to an idle and when it is idling
it is very erratic and often stalls. Any ideas please?
Regards Daniel.
