thom, for what it's worth and hopefully gives you some confidence , my 1 1/2" gates tracks to the left side of the rear pulley but when pushing the bike backwards it will track to the right.... i have ridden the bike enough since doing the wide belt conversion that if she was going to come off then she would have come off by now. so lets see, you have the belt switched out in 25 minutes right? how much time invested in worring about the tracking issue? 
just meesin' with ya, last thing i would want is to lose a belt while spinning down the highway so i can understand you being a little paranoid about it...... 
yeah I was saying to myself, "..all that studying and staring at the service manual (like I usually do before i R&R) in order to figure out how to do it quickly and I end up spending more time on it trying to get the right damn adjustment!..."
I was careful and methodical when I was doing it, thinking each step thru....I really think it's this particular belt cuz I have done this before with the old oem belt and never had it track this drastically before...it's just the damn tracking to the left that I have never seen before and was throwing me off. I guess what I learned out of all this is that each belt will act differently and will favor one side or another acceptably...
The bright side is all this learning will pay off as my buddy's ask me to help with their Warrior....
Oh, I'll let you in on a little secret also...I wash my hands alot, like every 5 minutes when I am just sitting watching tv or something. My wife says I'm borderline OCD cuz there are certain things that I obsess about...
