S&S Cycle 124" Hot Set-Up Kit w/ Big Bore Cylinders Cams Pistons Harley 99-06
This 124" big bore/stroker Hot Set Up Kit® transforms a stock 88" engine into a 124" monster.
This kit includes
- S&S 4-1/8" bore pistons
- Big bore cylinders finished in wrinkle black powder coat
- Dynamically balanced 4-5/8" stroke three piece flywheel assembly complete with S&S heavy duty connecting rods and intergal mainshafts
- S&S 640 gear drive Easy Start camshafts
- S&S chromoly steel adjustable pushrods
- S&S premium tappets
- S&S Super Stock 91cc cylinder heads.
When installed the kit yeilds a 124" engine with a compression ratio of 11:1. Although the engine is .960" taller than stock, there are no frame clearance problems, and a stock EFI Throttle body will fit because the manifold mounting surfaces of the heads have been specially machined to fit a stock length manifold.
No fuel or ignition system is included. However, for the best results, a larger carburetor of EFI throttle body, performance intake and performance exhaust are recommended. The EFI system must be recalibrated.
Note: Installation kit required for proper installation - sold separately. 1999 Twin Cam will need to use the splined cam drive OEM 25716-99
Note: Cases will need machining.
