Description CSR 124″ High Compression Big Bore Kit The CSR 124″ High Compression Big Bore Kit is one of the best cylinder kits available for the Milwaukee-Eight platform. This kit upgrades a factory 107″ engine to 124″ and works well for riders who want more power while continuing to use their existing camshaft. In addition, head work is not required for installation, although it can be added later for even more performance. The kit includes cylinders, pistons, rings, head and base gaskets, and a complete top-end rocker box gasket kit, making it a true bolt-on big bore solution. This kit pairs exceptionally well with the following camshafts: Zipper’s Red Shift 468 Cam S&S Cycle 475 Cam Wood 22XE Cam T-Man 216 Cam Star Racing 30/30 Cam Optional Add-Ons For best results, many customers choose to add the following supporting components: Feuling 3007 ARP Head Bolt Kit or S&S 900-1006 Head Bolt Kit T-Man Cylinder Head Breather Valves or Feuling Cylinder Head Breather Valves CSR 62mm Throttle Body Zipper’s 7.1 GPS High-Flow Injectors
