Exit the ordinary with Revolution Performance big bore kits for your Harley-Davidson, direct from J&P Cycles. Back in 2002, Revolution Performance changed the game by designing bolt-on big bore kits that utilized nickel-silicon carbide plating. Instead of using the dated cast iron sleeved cylinders, riders could now replace it with an all-aluminum plated cylinder. The results were earth shattering, and riders immediately experienced more power gain with a larger displacement. Not to be overlooked, big bore kits from Revolution Performance Motorsports run at lower temps compared to cast iron cylinders, which translates to longer operational life as well. Then continue your pursuit for engine excellence by working on your Motorcycle Engine Lower End and adding a performance Oil Cooler from J&P Cycles.
