The Fuel Moto 98" Big Bore is a complete kit with the highest quality components all of which have been extensively tested in house both on the dyno as well as in real world conditions. This kit is available for 99-06 Twin cam 88" motors and delivers absolute top level performance.
These custom forged pistons from CP Carillo are customized for this big bore kit at 10.0:1 compression. The ring end gap is already set and are simply ready to be installed.
The standard 98" kit requires you to send us your OEM cylinders where they will be serviced and returned back to you with the big bore kit. If you were looking for a quicker turnaround we also offer a core exchange program for OEM cylinders. If you are looking for an upgraded cylinder we also offer the Fuel Moto Extreme Duty Cylinders for $299 with no need to send Fuel Moto your OEM cylinders. The cylinders are a core component for reliability for any big bore kit and we offer the very best with the Extreme Duty Cylinders. These cylinders are designed for maximum durability and top level performance which feature a centrifugally cast ductile iron sleeve and are 100% made in the USA.
At the heart of the 98" big bore kit is the Wood Performance RCC kit. This kit includes a hydraulic cam plate, oil pump, inner/outer cam chains, cam sprockets, tensioners and all necessary hardware to bring your cam chest to the 2007 & newer specification. The included cam plate accepts the unique Wood Performance conversion cams rather than OEM styled bolt in cams. The RCC kit is a robust platform to build the 98" kit to your needs while providing extended reliability.
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-6-6R or TW-555-6R. Please note that for the 1999-2004 H-D models the use of the TW-555-6R cams will require updated valve springs or our Level B CNC cylinder heads. Give us a call at 920-423-3309 and a Fuel Moto technician will assist in finding the best cams to meet your needs.
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.
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.
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 bearings 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.
You have done all of your research but maybe you still have a question. The technicians at Fuel Moto have the answers and would welcome your call. With every Fuel Moto big bore kit purchase we include unlimited technical support. Shoot us an email at firstname.lastname@example.org or give us a call at 920-423-3309 - we will work together to get you up and running.

Description: The Fuel Moto Extreme Duty cylinders are designed for maximum durability and top level performance for Twin Cam engines. For our 107" big bore kits they are available with a heavy duty centrifugally cast Ductile iron sleeve.

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.
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.
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.
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.
