I have some new go kart motor clutches
 

I have three 5/8 35 chain clutches, 3 5/8" 40/41 chain clutches and two 1" shaft clutches. I'm not sure who makes the 1" diameter clutches but all of the others are made by Max Torque. $25 for each of the 5/8 bore clutches plus shipping and $75 each for the 1" bore clutches. These are all brand new.

The 1" clutches are gone.
