[align=center]Recommended Upgrades for 2007 HD Twin Cam engine[/align]

The number of 2007 performance engines is increasing. But Nightrider.com still recommends staying with fairly conservative upgrades. We are only listing a few bolt-in cams right now that meet the performance needs for all but the most radical of engine builds.

Please be aware that complete exhaust systems and cam shafts are very specific to all 2007 96/110 CID engines and 2006 Dyna models. Exhaust systems for these bikes have bungs installed in them for the O2 sensors required to maintain EPA compliance. While any exhaust system can have O2 bungs welded into them, placement of these bungs is important and the chrome will be damaged when welding in a bung.

We will continue to expand the engine upgrades section as more parts become available for the 2007 bikes.

[align=center]Harley-Davidson Screamin' Eagle Warranty Issues[/align]

It seems that many riders believe that using Screamin' Eagle performance upgrades have no effect on their HD Warranty. Despite what the local HD Dealer may tell them, only HD parts that are listed in the 2007 Catalog with a "green light" designation can be installed on their bikes without having a negative effect on the warranty. This means that most Screamin' Eagle components will void the warranty on much of the engine.

While in some cases your local HD Dealer can "sneak" a warranty issue through Harley's process as a courtesy to its own customers, it is highly unlikely that another Dealer will extend the same courtesy.

No matter what your local Dealer may tell you, the explanation of the warranty listed above is an honest interpretation of how Harley-Davidson is now enforcing its warranty.

The chart below lists recommend parts for upgrades that can be performed to your 2007 Harley-Davidson. While the list is not all inclusive, it does contain a list of parts that Nightrider has extreme confidence in. These parts and suppliers have historically provided the type of components and upgrades that have above average performance.
