Primary SchoolJim Nasi Customs' 3-inch billet open primary drives are machined from 6061-T6 aluminum and have 356-T6 aircraft-grade aluminum pulleys. The pulleys are hard-anodized to reduce wear and increase belt life. The 3-inch belt is reinforced with Kevlar. The jackshaft assembly, clutch hub nut, and all other necessary hardware are included.

Uh, Where Does What Go?One deciding characteristic of a pro builder is the lack of guesswork involved in a bike's design. Let Custom Chrome take out the uncertainty factor for you with its complete drivetrain kits for Softail models. These kits include the company's latest RevTech engines and six-speed transmissions, and an updated RevTech chain-drive primary kit. The primary kit contains a 66-tooth ring gear with a nine-tooth starter pinion gear to increase starter-motor torque. The kit also maintains a higher primary ratio using a 25-tooth compensator sprocket and a 36-tooth clutch shell sprocket for easier starting. Also included are a RevTech Kevlar clutch, polished or black powdercoated high-torque starters; jackshaft; heavy-duty alternator rotor; stator; all mounting hardware; and seals, bushings, and gaskets (rectifier/regulator not included).

Don't Fret Your Weak ArmsAre you working out and lifting weights to compensate for that heavy clutch pull? You can cancel that gym membership, because AIM's VP92T clutch kit will reduce clutch pull about 7 percent from a stock setup by utilizing a centrifugal-force lock-up effect when more pressure is needed. The VP92T is designed for big-inch motors up to 124ci or up to 130 lb-ft torque motors with a stock clutch spring. The kit eliminates the need of a heavier spring for a big-inch motor.

Handle The Power If you want a strong powerplant, then you have to be prepared to manage the power. S&S engineers understand the demands of high-performance engines, so they designed a clutch to handle all the power they produce. A unique feature of the S&S clutch is narrow friction bands placed farther out on the rings than normal. Narrow might seem to be the wrong direction, but with the bands' outward placement they improve clamping power significantly and increase the available torque to turn the transmission. The new S&S clutch fits '91-'05-model Big Twins, has 11 friction and 10 steel plates, and can handle 150 hp to 200 hp with the optional spring kit-and it does so with less lever effort than a stock clutch. Additionally, the clutch includes a 66-tooth ring gear and a pinion gear to match for increased strength and reduced tooth breakage.

Low And LowerFor once it's OK to think low thoughts. The Drop Starter Slam Clutch (more easily referred to as the DSSC) is the latest offering from Baker Drivetrain. This design lowers the starter, which allows a lower center of gravity with a lowered oil tank and lowered seat height. With the DSSC the clutch is placed where the pulley would be located on a typical LSD motorcycle. The clutch weight is closer to the center of the chassis, so you have a more agile, better-handling motorcycle. The DSSC consist of a billet RSD setup, inner and outer primary, case, top cover, and shroud. All pieces are available in raw, show-polished, or spectacular chrome finishes.

Pearly WhitesThe expert dentists at Super Max have invented a method of removing the worn teeth of aftermarket aluminum pulleys and replacing them with a Super Max overlay pulley that is impervious to sand and gritty road grime, emits no noise or squealing, and claims to last well over 100,000 miles (as long as the recommended tensions and alignments have been adhered to). Super Max can modify most stock and aftermarket pulleys with 64, 65, or 70 teeth. The service is offered with a two-year warranty.
