MSTR W/PISTNS & PRM RINGS

Our value priced Fuel Moto SP 124" big bore kit takes your 107" M8 engine to 124" with no engine case boring required. It was developed to work with a wide range of M8 cams and components. The 10.75:1 lower compression kit works especially well with shorter lift/duration bolt-in cams such as the Wood 22XE & 22XD, Redshift RS-468, Star 30/30, S&S 475, CR 480 and other similar grinds. We also offer this kit with 11.0:1 pistons for use with a bit larger camshafts, etc. Includes custom piston kit, new cylinders (globally sourced by Daytona), and Cometic MLS heads & base gaskets. This kit works on 2017-later Milwaukee-Eight 107" engines (air cooled & twin cooled) Touring and Softail. Works with stock or ported heads. Requires an exhaust system, air cleaner, EFI tuner, clutch spring and/or lockup, and larger fuel injectors for Milwaukee-8 engines. Professional installation recommended.
