I pulled the good-ol' Super-B from my Twincam Softail and bolted it on the 883 Sportster. Going from 1449 down to 883 cc I thought it needed different jetting, but to my surprise jetting is still perfect. Altmann AMM-P3 ignition does the spark timing with stock ignition coil. The EFI module is still in the bike, and controls the speedo. All security module and fuel-gauge functions work as before. The Vance & Hines short shots look really cool and with the Super-B I have lots of power and excellent torque. Super-B works flawlessly on the 883. (less info)
