Harley Davidson 48 2011: https://ultimatemotorcycling.com/2010/11/10/2011-harley-sportster-48-review/

Hardware Installed:

  • Vance & Hines sideshots exhaust system: http://products.vanceandhines.com/store/harley/46035/
  • Joker Machine Hi Performance Air Cleaner: http://jokermachine.com/products/harley-davidson/air-cleaners-fuel-injection-carburetor/sportster-high-performance-air-cleaner-assy.html
  • Power Commander V by DynoJet: http://www.powercommander.com/powercommander/products/PowerCommanderV/powercommander_v.aspx

Problem Details:

I get a miss when idling. The bike backfires quite a lot when gearing down.

Resolving the problem:

Thanks to Stan Lass from DynoJet, the problem was quick to resolve.  All I had to do was advance the fuel on 0% throttle for 500/750/1000/1250/1500 to +5.  The bike sounds smooth and the backfiring when gearing down is notably reduced.  It took me a year to make the change, but the difference is astronomical!
