Whether you dislike the look of your stock “ham can” air cleaner or are looking for some sort of performance gains, a new intake system is always an easy and good-looking parts swap for your Harley. Take for instance this H-D Evolution engine. Sure it has seen better days, but this bike still runs strong, so we are going to keep riding it until it blows up. That’s not to say that we aren’t going to fix up the old dog with a few new parts before its demise. And so we decided to start with an Arlen Ness Big Sucker air cleaner kit and top it off with a San Diego Customs Flying Saucer cover. This is a very simple and quick installation and only requires basic hand tools and a person with a basic knowledge of how to work on a motorcycle. Follow along as we show you how to do it right.
