Compu-Fire Starter Gear Drives

Compu-Fire starter gear drives and gear sets are upgraded aftermarket starter components primarily designed for Harley-Davidson© Big Twin motorcycles. Key features and design: * 10/84 gear ratio: These sets typically feature a 10-tooth pinion gear matched with an 84-tooth starter ring gear * Increased torque: The 10/84 configuration delivers roughly 15 percent more starting torque than many stock gear setups * Durability: The gears are forged from hardened 8620 carbonized steel to resist wear, chipping, and tooth breakage * Fix for weak stock ratios: They're often used to replace problematic or weak stock gear configurations (such as late-model 10:102 ratio gears that are prone to snapping or grinding) * OEM compatibility: The gears are engineered to drop into place and work with stock OEM clutch baskets * Common product types: -- 10/84 gear sets: Complete replacement kits are tailored to specific Harley-Davidson© Evolution and Twin Cam Big Twin model years (typically ranging from 1990 through 2006) -- Replacement drives / pinions: Individual components like the Compu-Fire Gen III replacement drives and standalone 10-tooth replacement pinion gears for routine maintenance or repairs

Compu-Fire Gen 3 Starter Solenoids

Compu-Fire Gen 3 starter solenoids are engineered to provide high starting power with strong torque, even for large displacement and high-compression engines, by using a powerful neodymium magnet and planetary gear reduction. Key benefits include the ability to handle significant load without requiring auxiliary compression releases, efficient power delivery that draws less battery current for the power it produces and a compact design that incorporates advanced features like a high torque clutch and center shaft alignment. Product Overview: * Replacement solenoid for Compu-Fire Gen 3 Starters * Housed in a short, compact package, making it easier to fit into tight engine bays, and it incorporates powerful ultra-strong neodymium magnets and a high torque clutch * The combination of powerful internal components, a robust gear system, and efficient power management contributes to the solenoid's reliability and longevity * Features a polished billet with a chrome finish, providing a visually appealing look * Designed to handle engines with high compression ratios, making them suitable for performance or built engines * High starting power and torque—powerful Neodymium magnets generate extreme power, allowing the starter to turn over high-compression engines effectively * Improved cold starting—the extra torque and power provided by the Gen III can lead to easier and quicker starts, especially in cold conditions or with engines that are difficult to turn over * Incorporates a removable jackshaft coupler and true center shaft alignment through its use of three planetary gears
