Over the years I have had several generations of engines in my Super Glide. The last version is by far the best. I took it apart myself and took all my parts to Jack Larson with Larson Machine in Belton, Missouri. He did a complete work over and built me a strong motor with 88 hp and 88 ft lbs of torque that functions great as a reliable daily driver. The Mikuni carb and Thunderheader complete the package.
I picked up the finished motor at his place and then reassembled the bike. For a guy like me it is a good feeling to know you have seen all the working parts of your motorcycle first hand. The only piece I haven't had apart at this point is the transmission.
I highly recommend dealing with Larson if you need/want any motorwork. He has been around a long time and knows what he is doing. He has been wrenching longer than I have been alive, and I will be 40 this May. Jack runs ads in Wide Open Magazine and operates out of his garage in Belton. He does work for many of the bike shops/dealers in the KC area.
Here is my paperwork (prices omitted).
Here is my dyno sheet from Worth North. The dyno process there was a fiasco. I will write more about that later. I have learned not to expect much from people who were working at Home Depot a few weeks ago...and when you go back they aren't there anymore.
