fits  06-17 96″ Dyna; 07-17 96″ Softail; 07-16 96″ FLT/Touring (NU)

Silver powder coated cylinders. No need to bore-out the cases. With 3.927″ bore S&S feels this is the largest bore possible that can be safely used with stock bore crankcase spigots. With a set of S&S .585 cams, S&S teardrop air cleaner and S&S mufflers the 106″ S&S test bike showed a very noticeable 60 to 91 horsepower jump. The forged pistons requires no flywheel re-balancing and valve pockets are enlarged to acommodate oversize valves and higher lift cams. Fits stock 4-3/8″ stroke 96″ Big Twin models and increases capacity to 106″. 10:1 CR with stock 89cc cylinder heads and 10.7:1 CR with S&S 79cc heads. Note: S&S does not recommend boring OEM cylinders to a bore this large because of possible failing of structural integrity. Just one piston oversize (917501) available for this kit.
