Is there any real drawback to not using the clutch drum? I am more than likely going to put a solid sprocket on the motor shaft in order to get a freewheel back in the primary gear. Any drawbacks other than starting? I NEVER engage the throttle until I'm going at least 8 mph so no worries there. I just need some insight from the experience here. I am looking to use an 8 tooth on the motor shaft and a 40 tooth on the pulley shaft.
