MILWAUKEE, Wis. - Now that 2014 Harleys are hitting the streets, it’s time to start the modding.

While the new Twin-Cooled 103 c.i. motor found in the Ultra Limited and TriGlide is significantly stronger than the old 103, more power in never enough. For riders who want the ultimate in H-D Big Twin power, Harley-Davidson has just announced its new Screamin’ Eagle 110 Cubic Inch Stage 1 Kit ($1,998.95), which allows riders to experience the full power of the 110 c.i. engine found in the CVO touring machine.

The 110 Kit is fully street legal and comes with everything that you need to turn the Twin-Cooled 103 into a Twin-Cooled 110, including four-inch forged pistons and cylinders, SE-255 camshafts, and cylinder heads with automatic compression release.

The Screamin' Eagle cylinder heads and forged piston combination offers a 9.3:1 compression ratio for easy starting. “Screamin' Eagle 110” cylinder head medallions also show off the engine investment, making it clear that this isn’t the same-old, brand-new precision-cooled 103.

The kit also includes all required gaskets (except primary cover and transmission interface gasket) and hardware to complete the installation, but does require case boring, the separate purchase of an Automatic Compression Release Wiring Harness, and ECM recalibration. The separate purchase of cam spacers and professional installation is recommended.

This kit fits the 50-state 2014 Ultra Limited model.
