Yes, 2000 was the millenium edition bikes. I had an 01 with fuel injection, wish I had a carb on it. The fuel injection was Harleys Delphi and it was rough with low rpm where the motor shined. Probably the most fun you can have on a harley.

The Cylinders are aftermarket , likely a nicasil plated 1250 kit , there were no "millennium" markings on stock cylinders. The injection was Buell's DDFI system with a Walbro throttle body , Buell never used the Delphi system .
Those bikes had special paint and trim , not a lot were made .

Buell was Harleys test bed for Delphi in 2000 to 2002. If the bike is millennium edition it will say so on the graphics and the motor. An x1 has better heads than the m2 also. In 03 they switched to the ddfi system used until 2010 when they closed.

Wrong !
I worked at a dealership from 1984 until 2012 , attended well over twenty factory training courses during that time , including a DDFI course in York , PA - March 2001. DDFI began in 1999 when Buell first produced fuel injected bikes , I gotta say the beginning was flawed with bikes that ran poorly , I repaired lots of them and reflashed pretty much every 99 I worked on .
Let's get this straight ....... Delphi is Harley , DDFI is Buell , the two systems shared nothing , the DDFI had several key differences , one being the use of an O2 sensor , Harley/Delphi bikes didn't have O2 sensors until 2007.
I was the Buell go to guy at the dealership , I've owned several of them .
The only millennium markings on that model were the timing cover plate riveted to the cam cover and the gas cap , yes there was a paint / decal scheme unique to that bike , nothing special though.
There were a couple of other special models made back then , numbered special editions , like a race stripe X1 and a Carbon fibre X1
The heads on all Buells made from 2000 to 2002 - X1 , S3 and M2 , were the same , all were equipped with what was know as "Thunderstorm" heads , a big valve , closed chamber design , pre 99 M2 heads were known as "lightning" heads , different but still a nice design.
When the tube frame bikes were dropped in 2003 and the XB series was born , the DDFI was carried over and used until the end of those models.
The 1125R used yet another system...............

My second Buell was an '09 1125R. That was quite a machine!
