Hey guys. Just wondering if there is a preferred year governor spring that is popular. I have read a fair bit eluding to the 2003 kx250 spring being soft and most people preferred the 2004 spring. There was enough material that spoke of the 90-91 spring too. It seemed different springs change the power valve operating range. Again its only what I read and I have no idea about cross referenced parts. I actually found most of the info on other sites, Any feed back appreciated.

kx250 03 needed a extra shim put in ,1mm thick that and a pc pipe did wonders.One of the magazines had a article on it years ago plus the Kawasaki race tuning information had its as well,p/n92026-1590 it goes between the bearing and the existing spacer it help the low to midrange speed transition smooth ,it worked on the 03 I had.The spacer is fairly cheap as well.
