{"product_id":"mcs565150","title":"S\u0026S 124\" Twin Cam Hot Set-Up Kit with Heads. Black – 2006–2017 Dyna; 2007–2016 FLT\/Touring","description":"\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eBlack wrinkle painted with highlighted fins. Will upgrade your stock 96\" or 103\" engine to 124\" capacity. Kit comes complete with stroker flywheels; big bore cylinder \u0026amp; flat-top piston kit that gives a 10.8:1 CR with the included 91cc high flow heads. The 640 Easy Start gear driven cams provide the lift required to let this engine breathe but insures easy turn-over with stock starter \u0026amp; battery. Note 1: Stock cases must be machined to accept the larger 4-1\/8\" big bore cylinders. Kit adds .096\" to engine height. Note 2: You will build a serious high performance engine. It is therefore not compatible with stock ignition and stock (too small) throttle housings. A large throttle housing; as the 558678 S\u0026amp;S 58mm single bore unit; and high performance ECU is required. Carbureted engines will require a ignition system with adjustable advance curves and large carburetor; as the S\u0026amp;S Super G or similar. Kits are machined to be compatible with stock length manifolds. Note 3: S\u0026amp;S recommends MCS 978519 JIMS crankcase bearing insert; for 03-17 Twin Cam models; to replace the stock roller bearing for the stronger early style Timken bearing. See MCS 978517 for required JIMS tool. The correct Timken bearing can be ordered as MCS 508960 \/ OEM 9028.\u003c\/p\u003e\n\u003ch2\u003eFitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e06-17 Dyna\u003c\/li\u003e\n\u003cli\u003e07-16 FLT\/Touring (Excl.
