look, the guy asked for sources on a chain set up for his build. which is how I ended up on this thread. one of the most forum-annoyances is when everyone avoids the question, and tears you apart criticizing your build. calling you everything short of stupid. it's disrespectful and makes forum numbers drop.

for what it's worth, if it's still relevant to your build, guys are using 520 or 525 countershaft sprockets. and a few Ducati sprockets mesh with the XG's splines perfectly. your gonna have to do something with the rear wheel drive though.

The belts last 80K to 100K on Harley. Do not need to be adjusted nearly as of often and for the miles and years of of service cost far less

Performance model?
The Street is not a "Performance" model, it is Harley's entry level motorcycle, it has a belt because belts are reliable and lower maintenance than a chain. Most new riders don't want to mess with the maintenance of a chain. Real performance junkies, racers ect.... don't mind doing that maintenance.

Chains came before belts. So your comment regarding belts being archaic is incorrect.

Belts are available in various lengths and in many bikes, various pulley sizes are available.
I've seen 883 Sportsters break a belt. Granted the belt was over 20 years old and the bike had almost 50,000 miles on it. But I have seen it happen because it was on the 883 Sportster in my sig line that my daughter rides.

I'm pretty sure early motorcycles used leather belts for the drive, not a chain. The clutch adjusted the tightness of the belt.

You can see the belt in the pictures in this article:

I would not replace the belt with a chain, it's a retrograde step.

Peace.

Here is an article about a guy who used a Street 750 to build a flat tracker.

http://www.bikeexif.com/harley-david...0-flat-tracker

Sounds like you will need to do some very custom work.

From the Article:

Everything was going swimmingly until it came to the wheels and the chain conversion. “This is where most of the headaches are found,” says Thor wryly. “First off, we made our own hubs from a big ol’ piece of aluminum.”

See See are using a 520 chain on this bike, so that they could use Barnes-style quick change sprockets. “Using a 520 chain means you need to find a 520 or 525 countershaft sprocket.” Hot tip: A Ducati countershaft sprocket fits the splines.

But for a bike that was designed to be quick, customize and rip up the streets, the belt drive is just so constraining.

We will agree to disagree for sure. Relaible non customizable gearing has it's place for touring machines but on little scoots, I beg to say it's the wrong drive for that application.

Best,
Low power, see the load that bike pulls. Go broke keeping chains on it. Old school was not as cool as some like to think it was. I have a friend that has 30,000 miles on his 750 Street Belt still like new.
750 Street tugging a sidecar no belt issues.
