These cylinders feature hi-strength steel liners which allow for "Drop In" installation of 110" cylinders (4.000" bore diamter) without boring the cases on H-D Twin Cam engines with a 4.375" stroke.

The cams are the workhorse of any big bore kit which is why every single Fuel Moto big bore kit has a set Wood Performance Knight Prowler cams inside. We offer several choices to customize your big bore kit to your needs such as the Wood Performance TW-777, TW-888, TW-8-6, TW-999-6 or the TW-999-6A cams with additional options available as well. Give us a call at 920-423-3309 and a Fuel Moto technician will assist in finding the best cams to meet your needs.

Wood Performance Alpha Series Directional Lifters

Wood Performance Alpha Series Directional Lifters

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 brand new Wood Performance cams we also install the brand new lifters on each and every build we perform in house.

Fuel Moto Quick Install Adjustable Pushrods

Optional Accessories


Level B CNC Cylinder Head Porting

Level B CNC Cylinder Head Porting - $879

Description: The Level B CNC Cylinder Head porting service is our premium street performance head. It was developed over hundreds of dyno runs with a wide range of components for the best overall performance gains. This service makes exceptionally broad torque along with high RPM horsepower and allows for use of increased compression and a wider selection of camshafts with the 110" big bore kit.

Level C CNC Cylinder Head Porting

Level C CNC Cylinder Head Porting - $995

Description: The Level C CNC Cylinder Head porting service was designed for those looking for maximum horsepower. The Level C cylinder porting service is fully CNC machined (including the combustion chamber) which offers unmatched consistency and accuracy. The Level C head porting service carries the horsepower slightly further along with the use of 5/16" valve stems and .650" lift valve springs which allows for the use of higher lift camshafts and increased compression.

Fuel Moto / AIM Variable Pressure Clutch

Fuel Moto / AIM Variable Pressure Clutch - $285-400

Description: The Fuel Moto / AIM variable pressure clutch is the most cost effective and powerful kit available to upgrade your H-D stock clutch to handle the added power of the Fuel Moto big bore kit. Developed by Fuel Moto with a specific weight combination to suit our engine packages this clutch will support up to 130 horsepower / torque with the OEM spring and up to 150 horsepower / torque with the optional heavy duty spring all with up to 7% reduction in clutch lever effort.

Manual Compression Releases

Manual Compression Releases - $100 / pair

Description: When building your engine up from a 96ci your cylinder heads are not equipped with any sort of compression release. With the increased compression in a big bore kit it is highly recommended to have us install a set of manual compression releases. These simple push-button releases will prevent any excess wear to your motorcycle. Manual compression releases are not required when building your engine up from a 103ci engine as your cylinder heads are already equipped with compression releases.

Jagg Oil Coolers

Jagg Oil Coolers - $399-550

Description: If your motorcycle is not currently equipped with an oil cooler or you are simply not satisfied with the stock oil cooler's performance the addition of a Jagg oil cooler certainly makes a difference. There are several options to choose from such as a basic slim line oil cooler all the way up to a fan assisted oil cooler which utilizes a fan to pull air across the oil cooler when your motorcycle is not in motion.
