4 Valve Hemi Heads for Harley Big Twin Engines

rpmhemi.jpgEver hear of a V-twin Evo or Twin Cam motor with approximately 85% of available torque coming in at approximately 1500 RPM? We have! At RPMHemi.com we do it all day long with our patented 4 Valve Hemi Bolt on Head Conversion Kits. “This is simply the best performance bolt on for the buck in the V-Twin market!” states Phillip Holmes, VP of Marketing & Sales for RPMHemi.com. You can estimate an approximate 20% power gain. This is a proven technology with both street and racing applications.

How it works: Utilizing our patented 4Valve system in a hemispherical combustion chamber we can increase airflow 1.5 times, increasing the compression ratio while maintaining a 25° spark advance, which gives an equal full burn in the chamber, while preventing pre detonation. All this in a package that is ¼” lower than stock heads. Our headsets and engines are also low in emissions.

RPMHemi.com manufactures their patented 4 Valve Hemi Head Kits and sells complete 97”, 107” and 114” motors with or without our 4Valve Hemi Heads and we have our patented Ram Chamber for single and dual carburetor V-Twin applications.

Currently, we have several OEM motorcycle manufacturers testing our products and all looks good.

Big Dog 2009 Wolf preview

280208amd.jpgBig Dog Motorcycles used the annual V-Twin Expo in Cincinnati to provide dealers with a ’sneak peek’ of the first of the new models for its proposed 2009 model range. Big Dog’s Wolf is due for an official release in September of 2008. However, at the time of going to print the final specification has not yet been clarified.

What is known about the bike is that the frame will feature a single downtube fit with a radical swingarm design. The tire sizes will be 130/60R-23 front and 220/50R-20 rear. The narrower rear tire follows a trend which company founder and CEO, Sheldon Coleman, outlined at the company’s recent dealer presentation in California, and which has been set by this year’s Mutt, with its 250-section tire deviating from the company’s more normal fitment of a 300.

280208amd2.jpgMotive power for the Wolf will be provided by an S&S 121ci X-Wedge, with electronic fuel injection, mated to a six-speed BDM Balance-Drive transmission.

The company says an extensive chrome package will be offered as standard and there will also be an optional highly-styled saddlebag.
