S&S CYCLE - 330-0299 - Camshaft Kit - Easy Start - MR103 Chain Drive - Twin Cam '07-'17 | Dyna '06
Chain wear is one of the most common causes of lost power and trail-side repairs, and the S&S CYCLE 330-0299 gives you a precision-built chain designed to outlast the competition. Allows for easy start by initially reducing crank compression, but once the engine starts and rpm increases, the compression release lobe is centrifugally retracted and the engine runs normally, with full compression, and without any loss in performance. Designed as bolt-in cams for 103” engine with stock 9.7:1 compression ratio up to 10.5:1, ensuring strong pin retention. More power across the rpm range best results from 2500 rpm - 5500 rpm, and includes camshafts, gearcover gasket, bearings, retaining ring, o-ring, threat lock and instructions give this chain the internal toughness to resist constant flex and impact loads. Made in the USA. Whether running a practice bike, race machine, or trail bike, the 330-0299 delivers consistent performance. Sold as a complete kit.
