⚡ At a Glance
- • Torque Delivery: More low-end torque for stronger take-off and better hill-climbing
- • Best for: Go-karts, mini bikes, ATVs and other small vehicles needing improved acceleration
- • Not ideal for: Applications requiring integrated hands-free or electronic control systems
Comet 30 Series belt-drive torque converter kit increases low-end torque for stronger take-off and smoother acceleration. The complete kit includes drive and driven clutch pulleys, belt, aluminium engine mount plate, built-in jackshaft with sprocket and both 10t and 12t sprockets for common chain sizes.
Stronger Low-End Acceleration – Thanks to Comet 30 Series belt-drive conversion
Belt-driven driver and driven pulleys change the effective transmission of engine torque so the driven pulley multiplies torque at low engine speeds while allowing higher speeds as rpm rises. Driver clutch bore measures 1" (24.5mm) and the driven unit overall diameter is 6" with a 5/8" driven pulley.
Improved take-off power and smoother acceleration enhance responsiveness on launches and when climbing gradients.
Broad Fitment – With bolt-on compatibility for horizontal-shaft small engines
Mounting design suits engines with a horizontal shaft and is described as compatible with Briggs, Clinton, Honda and clones, Kohler, Lifan, Robin and Tecumseh motors. The kit bolts on to most such engines using the supplied aluminium engine mount plate and hardware.
Easy adaptation to many popular small engines makes the kit a practical upgrade for a variety of go-karts and mini vehicles.
Ready-for-Retrofit Installation – Thanks to a complete kit with jackshaft and mounting plate
Kit contents include both drive and driven clutch pulleys, a belt, aluminium engine mount plate, built-in jackshaft with sprocket, all mounting hardware and instructions. Both 10t (for 40/41 chain) and 12t (for 35 chain) sprockets are included to match common chain sizes.
Full set of components reduces the need to source extra parts, simplifying installation for DIY mechanics.
