Package 1: INTAKE AND EXHAUST

One of the most cost effective ways to improve motorcycle performance is a high flowing air cleaner kit and a set of high performance slip-on mufflers from S&S®. These parts are also required components of any more serious performance package. A combination of an S&S performance intake and exhaust is the easiest way to get some instant gratification. They provide the best horsepower per dollar you can get, and lay the groundwork for further upgrades. Let the experienced team at 2Boss Performance get this upgrade installed for you by calling 855-593-5433.

PACKAGE 2: CAMS AND PUSHRODS

The addition of cams is the next step toward higher motorcycle performance. Several types of cams are available, and it is important to decide what cams are best suited to your immediate needs and what cams will be needed to achieve your long-term goals. If you can choose cams that will work for both, you will save money. For more torque we recommend the S&S® 551 cams for dressers, and the S&S 583 cam for Dyna® and Softail® models. For more top end horsepower, we suggest the S&S 585 cams. Dealer installation of cams is recommended, and EFI tuning is generally required. We recommend the Harley-Davidson® Race Tuner or Dynojet® Power Commander® for EFI tuning. Call us at 855-593-5433 to get more information.

PACKAGE 3: 97” & 106″ BIG BORE KIT

The next step is to increase the displacement of your engine. The S&S® 97″ Big Bore Top End Kit for 1999-’06 88″ engines or the 106″ Top End Big Bore Kit for 2007-up 96″ engines are an easy and cost effective way to do it. Simply replace the stock pistons and cylinders with the S&S 106″ Top End Big Bore Kit. No machining or flywheel rebalancing required. Cams, exhaust, and intake components from steps 1 and 2 will work great with the 106″ Big Bore Top End Kit. Call 2Boss Performance at 855-593-5433 to set up an appointment.

PACKAGE 4: CNC PORTED HEADS & FUEL SYSTEM UPGRADES

After the displacement of an engine has been increased, and high performance intake, exhaust and cams have been installed, the next step is to make the heads flow better. Feed that engine some more air!

Take full advantage of the increased displacement of Step 3 with high flowing CNC ported stock heads. Complete the
transformation with an S&S performance carburetor or big bore EFI throttle body.
