Comet 340 Series Torque Converter System (Symmetrical) for Go Karts & Mini Bikes

Comet 340 series torque converter system is for 2 or 4 cycle engines up thru 8 hp. Designed especially for jr dragster, go karts and mini bikes. Uses the same 3/4" top width belts as Comet's 20 series. Drive clutches come uncalibrated so roller kits and spring kits must be ordered separate. Drive clutches are available for both 5/8" and 3/4" bore engines. The driven clutch is available with either a 5/8" or a 3/4" bore.

    • The following engagement chart is based on static rotation testing only. In actual selection of components, the weight of the arm relative to the horsepower being transmitted should also be considered.

      NOTES: Although different combinations of weights and springs might result in the same engagement RPM, the heavier weights and stronger springs cause quicker upshifts (lower RPM) and slower backshifts (lower RPM).
