Why is my 2000 KX250 more responsive at part throttle before it is fully
warmed up?
I typically start the bike with the choke, then immediately take the choke
off and vary throttle positions to keep it running. Then when I can feel some
heat in the radiator, ride it around in an open field until fully warm. When
the bike is being riden in the open field, before it is fully warmed up, is the
most responsive at part throttle it is all day. I have had the bike for 2 years
and it has always been like this. It is no different in the winter than the
summer. I have changed pilot jets many times. From the stock 52 all the way
down to a 40. Checked and changed float height, varied needle clip positions.
These changes did effect how the bike ran, but it was always more responsive
when warming up. Why?
Thanks,
Steve
