Except for a 48mm S&S; Super E Shorty carb and Chopper Dave air filter, the 55-cubic-inch V-twin is essentially stock, right down to the original '58 magneto. The chassis, however, isn't: A replica of Harley's bolt-on dirt-track hardtail came from Craig at Front Street Cycle. That's a newer Sporty fork holding up the other end, shortened and converted to carry the original XLCH front hub. Akront rims carry Michelin trials tires. What rear suspension there is comes from a pair of 4-inch springs under the one-off solo saddle.
