GYMMEDS Torque Converter 30-Series 3/4" Bore Kit for Predator 212cc — CVT Clutch with 10T & 12T Sprockets

GYMMEDS 30 Series Torque Converter is a complete 3/4" bore replacement kit that upgrades Predator 212cc and other 3/4" crank engines with CVT clutch, dual sprockets, and drive belt for go-karts, mini bikes and small utility vehicles.

This torque-converter assembly is designed to be a direct-fit swap for popular Comet TAV2 30-series units and works on most 2–7 HP horizontal-shaft engines with a 3/4" straight crankshaft. The kit combines a lightweight aluminum driver, iron components and mounting hardware so you get a ready-to-install pulley system that adapts to #35 and #40/41/420 chain drive configurations. Engagement range is tunable, and the package includes both 10T and 12T sprockets to match common chains and final-drive ratios.

How does this torque converter improve small-vehicle performance?

The GYMMEDS converter smooths power delivery and reduces peak engine load by using a centrifugal CVT-style clutch mechanism. That helps the engine run in a more effective RPM band during acceleration and under load without electronic control. The included pulleys and belt transfer torque efficiently to the driven sprocket so your vehicle pulls more consistently.

• Includes 3/4" and 5/8" driver pulleys for common shaft and belt setups
• Aluminum and iron construction balances weight and durability
• Adjustable engagement range approximately 1200–3100 RPM via spring swaps
• Reduces engine stalling and eases throttle control under load

Will this kit fit my Predator 212cc or Comet TAV2 application?

The kit is intended for engines with a 3/4" straight crankshaft and is commonly used on Predator 212cc (6.5 HP) and similar 2–7 HP horizontal-shaft motors. It is a direct-replacement style for Comet TAV2 30-series torque converters and fits many go-kart, mini bike and small-tractor drive trains. Confirm your crank diameter and keyway before purchasing to ensure compatibility.

• Designed for 3/4" straight crankshaft engines with flat key
• Compatible with many Comet TAV2 30-series replacements
• Includes 10T sprocket for #40/41/420 chain and 12T sprocket for #35 chain
• Works on go-karts, mini bikes, ATVs, winches and small mowers

What comes in the box and how straightforward is installation?

GYMMEDS ships a complete parts kit so you can install the torque converter without hunting down extra components. The set contains pulleys, a drive belt, two sprockets, a mounting plate, a plastic cover and a full hardware assortment — plus two screw kits to suit UNF or metric shaft threads. Installation requires basic tools, some mechanical familiarity and verification of spring/engagement settings to tune performance.

• 1 x 3/4" driver pulley and 1 x 5/8" driver pulley included
• 1 x drive belt, aluminum mounting plate, plastic protective cover, hardware
• Two screw kits: UNF (American) and metric to match shaft thread standards
• 10T and 12T sprockets included; chain not supplied

How can I adjust engagement and tailor drive behavior?

Engagement RPM is set by the internal clutch springs and can be altered by changing springs or fine-tuning the assembly; stock engagement is about 2350 RPM. Swapping to lighter or heavier springs shifts the band toward lower or higher RPMs respectively, and gear ratio changes via sprocket selection affect acceleration versus top speed. No electronic tuning is required—only mechanical spring and sprocket changes.

• Factory engagement ~2350 RPM, adjustable roughly 1200–3100 RPM
• Change springs to modify engagement threshold (springs not included)
• Select sprockets to change final-drive ratio and acceleration
• Mechanical adjustments only; no ECU or electrical components

Who is this for: The GYMMEDS 30 Series Torque Converter kit is aimed at hobbyists, DIY mechanics and small-vehicle owners who need a reliable drop-in replacement for Comet TAV2 30-series clutches or want an upgrade for Predator 212cc and similar engines. It suits go-kart and mini-bike builders, maintenance shops, and anyone who wants a tunable, belt-and-sprocket drive solution for 3/4" crankshaft machines. Verify crankshaft size and chain type before ordering to ensure a smooth fit.
