Vespa Ciao variated vibration

Chris Carleton /

I've been experiencing lots of belt slap and grabbing at the underside of rear pulley. So I tightened the belt to the max. This didn't solve it but I think I bent the crank in the process now I'm experiencing lots of vibration and shaking. Ideas thoughts?

I dont think you bent the crank. have you tried a new belt? could just be uneven. Can you check the runout on the crank arm with the vario off? or on the rear pulley?

I had an anticipato crank where the lobes were untrue and it vibrated my feet almost off the pedals and wore down my cases it was so out of true.
