What is the 'Easy Start' feature on this camshaft?

The Easy Start feature is designed to reduce the load on your starter motor and battery when the engine is cranking. This makes starting your motorcycle easier and can help prolong the life of your starter components.

What other parts are recommended for installing this camshaft?

For best results and reliability, S&S Cycle highly recommends installing an S&S oil pump and cam support plate. An upgrade to a 2007-and-later style hydraulic cam chain tensioner is also advised for chain drive camshafts.

Can I use my stock valve springs with this camshaft?

Yes, for 2005 and 2006 model year engines, the stock valve springs can typically be used with the MR103 and HP103 cams. For other model years or if you have significantly modified your engine, checking spring compatibility is recommended.

Product Details

If you're looking to get more torque and horsepower out of your modified 1999-2006 Harley-Davidson Big Twin engine, this S&S Cycle MR103CE Easy Start chain drive camshaft kit is a solid option. It's designed to deliver more performance than typical bolt-in cams, especially when paired with larger displacement and higher compression builds. This kit is a popular choice for riders who want a noticeable improvement in their engine's power delivery.

The MR103CE camshaft features an Easy Start design, which helps reduce the strain on your starter and battery during startup. For 2005 and 2006 models, you can often use the stock valve springs with this cam, simplifying the installation. However, for optimal performance and reliability with chain drive cams like this one, S&S Cycle highly recommends upgrading to an S&S oil pump and cam support plate, along with a 2007-and-later style hydraulic cam chain tensioner.

To get the most out of this camshaft, consider pairing it with performance-oriented intake and exhaust components. While this kit offers a significant power boost on its own, the right supporting modifications can really unlock its full potential. This kit fits a wide range of Harley-Davidson models, including popular bikes like the Road King, Heritage Softail Classic, and Dyna Wide Glide from 1999 through 2006.
