MK136 Black Edition Engine - 550G Gear Drive - Oil Cooled - Race Only - M8 Touring

The S&S Cycle MK136 Black Edition engine is designed for high-performance M8 Touring applications, delivering superior power and durability for racing enthusiasts. Featuring high-flow cylinder heads with premium components such as oversized intake and exhaust valves, this engine ensures optimal airflow and combustion efficiency. The valves are extended by 0.030 inches to enhance valvetrain geometry, contributing to improved valve timing and engine responsiveness. Max lift valve springs of 0.605 inches further support high-performance camshaft operation, while the included 550G gear drive cam provides reliable, precise timing for aggressive engine tuning. Enlarged cooling passages around the exhaust seats promote better heat dissipation, maintaining optimal operating temperatures during demanding runs. S&S's exclusive breather boxes help manage crankcase pressures, ensuring consistent engine performance under race conditions.

The crankcase features patented dual-spray piston cooling jets, which improve piston longevity by effectively reducing heat buildup during high RPM activity. Precision-machined oil scrapers and an enlarged oil sump facilitate efficient oil circulation and flow, helping to prevent overheating and wear. The contoured oil sump design allows for seamless oil drainage back to the sump, ensuring steady lubrication throughout extended high-performance use. The MK136 package retains the stock engine height, simplifying installation without sacrificing power or durability.

This engine set includes forged pistons, a high-performance oil pump, and a cam support plate for added strength and reliability. Premium tappets and tappet cuffs ensure smooth valve operation, while billet aluminum covers and a sprocket shaft spacer provide robust construction and maintenance ease. The package also features Champion spark plugs and a cam cover badge, emphasizing quality and attention to detail. Made in the USA, the S&S Cycle MK136 Black Edition engine is a race-only powerhouse, engineered for ultimate performance and durability in demanding motorcycle racing environments.
