Re: [ST] Latest Tune Question

[jhseltzer <jhseltzer@xxxxxxxxx>]

Steven,

You're correct about the O2 sensor. Can't adjust the idle 
CO. My problem was quite severe. The bike stalled several 
times while I was riding it. A couple of times while I was 
in traffic. It's pretty hard trying to control the bike, 
watch cars around you, turn the key on and off and restart. 
  The surging was a problem too. As the problem got worse, 
it would surge at 50 mph.
