I have a 90 polaris indy sport my prob. is when its warm out sled runs for about 10 mins. then loses power. Have to let it cool down before it will run again.Several people told me it was cdi box.Installed new cdi yesterday,and it runs worse. Real boggy until about 1/4 throttle then runs like hell on stand.When u put it on ground it runs boggy and gets up to 20 m.p.h. topswhen u give it gas it idles up then bogs down, when u let off gas it picks up agian,any ideas?
