    Skip tooth sprockets??

    Just curious if anyone is running or has tried a skip tooth sprocket on a mini bike? Supposed to be a low drag option, but wonder if it leads to lost chains... WMS Tuck & Run #35 Split, Skip-Tooth Sprocket | 6435** | BMI Karts and Motorocycle Parts

    Jackshaft Sprockets

    I need a source for a type "C" sprocket with a 3/4'' bore. I can find all I want in a 5/8'' bore. All I can find in a 3/4'' bore are type "B" sprockets. I am sure they are available, I just cant find them... yet. Thanks for the help, Doug Edit; I need a 40/41 sprocket.
