When you switched to a narrow belt and pulley with your bike, did you keep the original front pulley? What was the tooth count of the new belt and rear pulley? What year wheel are you running? Same brake set up? Sorry for all the questions. Good to know stuff for future options..
Yes, you keep the same front pulley.. It will center itself once the rear wheel is aligned properly. If you wan to go to a narrow belt I have found that the 1 1/8" belt can with stand a lot of power. A few years ago I went to 2000 up rims and so I was able to run a stock 70 x 1 1/8" pulley coupled by an S&S 130 tooth belt. No issues with the brakes...
Don't forget the 99 down are 2.0" centers for the pulley and rotors and 2000 up are 2.2" centers....

When going to a narrow belt, if you keep the same tooth count on the two pulleys then the tooth count on the belt will be unchanged.
Like Tom I've gone to a 1 1/8" belt with later spec wheels and swingarm, have also upgraded to later spec Brembo brakes, which makes things a little more complicated. With my 30/70 pulleys I use a stock Sportster belt which, by good fortune, is two teeth shorter than my previous stock Touring belt.
Evolista wanna be here regarding the 30/70 pulley swap on my 2014 Slim I did same year I bought it.
Kept same belt. Only 7k mi. on it. But I did loose some belt adjustability setting. Almost half. Didn’t measure. I probaly should have put a sportster belt on it? Or would that have been too short on a softail?

Good info on the wheel swap. Thanks. Very happy with my stock setup thus far, but good to know as I'm looking through swapmeet parts. As I re-inspected my rear wheel before mounting it back on, the sprocket/tooth pulley is still in decent shape so it will serve for many more miles.
New Michelin Commander II and re-packed bearing. Last tire got 15K, so I'm really happy with them. Had balance bead in them also.
