CVT Torque Converter 30 Series Mini Bike Clutch 3/4 in - Reliable

In this review the CVT Torque Converter 30 Series clutch kit is judged as a practical replacement for Comet TAV2 Torq-A-Verters on small engines. It is aimed at DIYers and hobbyists who need a straightforward CVT clutch that fits 3/4 in straight crankshafts and 6.5HP horizontal shaft engines. The single biggest reason to buy is the complete kit packaging: a cast iron and aluminum clutch assembly, two sprockets, a jackshaft with sprocket, an engine mount plate and three high quality belts (plus two spares), which together simplify swapping a worn or incompatible torque converter.

Key Features

• Direct replacement compatibility: Designed to replace Comet TAV2 Torq-A-Verters 217610A, 218353A, 219456A and 219552A so installers can expect a familiar fit for many go kart and mini bike setups.
• Complete belt supply: Ships with three belts sized for 6-15/16 to 7 in center-to-center distance plus two extras so users have spares on hand and avoid immediate belt purchases.
• Multiple sprockets included: Comes with a 10-tooth sprocket for #40/#41/#420 chains and a 12-tooth sprocket for #35 chain to cover common chain drive options on small vehicles.
• Sturdy materials: Cast iron and aluminum construction aims to deliver better heat dissipation, durability and torque handling for small engines around 6.5HP.
• Adjustable engagement: Engagement range can be adjusted by changing springs and settings, giving users control over engagement point for different loads and uses.

Who It's For

This kit is best for owners of go karts, mini bikes, mini choppers or small tractors who have a 3/4 in straight crankshaft and a 6.5HP (212cc) horizontal shaft engine and who want a largely complete replacement pack to reduce extra parts sourcing. It also suits tinkerers who appreciate the included mount plate, jackshaft and sprockets for retrofits.

Those who should look elsewhere include buyers who cannot confirm their shaft size or have engines that are known not to accept standard TAV2 replacements; a few users reported fit issues on some 212 motors, so confirming measurements is important before purchase.

Pros & Cons

Pros

• Well packaged kit with belts, sprockets, mount plate and jackshaft that reduces extra shopping.
• Durable iron and aluminum parts offer good heat dissipation and longevity for light duty use.
• Includes both 10T and 12T sprockets, increasing compatibility with common chain sizes.
• Extra belts included give immediate spares for maintenance.

Cons

• Fit is mixed for some 212 motors, so buyers must confirm shaft and bore dimensions before ordering.
• Springs to change engagement range are not included, so fine-tuning requires additional parts.

Specifications
