    79cc Dyno #2 Build

    Another 79cc Dyno build. What I learned here: Use a solid rod in the seat post to minimize vibration (I am going to try making an extended seat post that goes to the bottom of the seat tube) Allow the centrifugal clutch to "float" on the crankshaft, in other words, do not tighten the grub...
