The Fuel Moto M8 117" big bore kit is a complete bolt kit with the absolute highest quality components, all of which have been extensively tested in house both on the dynamometer as well as in real world conditions to deliver top level performance. This kit works on 2017 Milwaukee-Eight 107" engines (air cooled & twin cooled) and when combined with the appropriate performance modifications offers output in excess of 120+ horsepower.
These forged pistons from CP Carillo are available in a specifically customized 11.2:1 compression ratio. The ring end gap is already set and are simply ready to be installed.
The Fuel Moto M8 117" big bore kit includes bore/hone & finishing your suppled OEM cylinders. If you were looking for a immediate turnaround we also offer a core exchange program for OEM cylinders, Fuel Moto has finished M8 cylinders on the shelf ready to ship with a reasonable core charge.
The camshaft is the workhorse of any big bore kit which is why every single Fuel Moto big bore kit has Wood Performance Knight Prowler camshaft inside. The Wood Performance WM8-777 has been built with this kit in mind and provides a strong power band offering early torque and high end horsepower alike. The WM8-777 cam works with stock valve springs & cylinder heads.
We all want more power with a big bore kit but would never want to sacrifice reliability. The Wood Performance Alpha Series Directional Lifters are a key component which addresses a common concern with the stock lifters which are simply not designed for the increased performance of a big bore kit. We are also a huge advocate of new parts on new parts so with a brand new Wood Performance camshaft we also install the brand new lifters on each and every build we perform in house.
The Fuel Moto quick install adjustable pushrods are the finest pushrods available. With a .095" chromoly tapered design which is engineered for maximum strength and durability these pushrods install right inside of the stock pushrod tube covers. Also included is our unique pushrod tube tool which holds the tubes in place for easy adjustment.
No one wants to be in the middle of a build and find that they are missing a gasket or o-ring to complete their build. With the Fuel Moto big bore kits all the necessary gaskets, o-rings and inner cam bearing are included. We have already performed in house stress tests to find the best performing parts to ensure your build is reliable for years to come.
