Optional Accessories


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.
