Product Details
If you're looking to get more performance out of your Milwaukee-Eight (M8) touring motorcycle, a gear drive camshaft kit like this 550G from S&S Cycle is a solid choice. This kit is designed to replace your stock camshaft and its associated chain drive system, offering a more direct and accurate way to control your engine's valve timing. It's a popular upgrade for 114 cubic inch and larger M8 engines, aiming to improve overall power delivery.
What sets this kit apart is the gear drive design. Unlike chain-driven cams, gears mesh directly, which means there's virtually no slack or stretch. This results in improved valve timing accuracy, especially at higher RPMs, and a more consistent engine performance. The 550G profile is specifically tuned for the M8 platform, offering a good balance of horsepower and usability for touring applications. Keep in mind that this camshaft requires adjustable pushrods and heavy-duty valve springs to function correctly and safely, so be sure to factor those into your build.
This S&S Cycle kit comes with all the necessary bearings, o-rings, and hardware to complete the installation, making it a comprehensive package. It's a well-built component made in the USA, designed to give your M8 engine a noticeable boost in performance.
