We finished rebuilding my 1929 Harley JDH earlier this week down at Wheels Through Time museum where I got to ride it about 50 miles before packing it up and heading to the AMCA meet in Oley.
To quote Carl Olsen who rode it a bit at Oley, it is as fast as a nice Knucklehead, a lot less weight and the brakes of a 10-speed bicycle.
During the critical break in period I like to get the bike up to operating temperature, then let it cool down, then do it again. Here is a photo we took of my 2-cam and one of Matt Walksler's flathead bobbers in front of a barn a few miles from Wheels Through Time during one of these sessions.
A shot of my 2 cam Harley at Oley with Trish (Dale's lady friend) and Mackenzie at the Wheels Through Time area - look closely and you will see my bike :-)
You can read more about the build in the pages of American Iron Magazine.
